Hi all,

Just wondered how official distances are recorded in US races and especially the Breeders Cup this year?

In the UK distances are calculated as follows....

TURF RACES
Good or quicker 6 lengths per second
Good (G to S) in places 5.5 lps
G to S (Good) in places 5.5 lps
Good to Soft 5.5 lps
Good to Soft (Soft) in places 5.5 lps
Soft or slower 5 lengths per second

AW
Polytrack (similar to pro ride) 6 lengths per second
Fibresand (as close to dirt as we get over here) 5 lengths per second.

Many thanks in advance if anyone can answer this one... :)

I appears you are asking what is the value of a beaten length.

Good luck with that. The values range from 7 to 10 feet depending upon who does the math, how much massaging they do to get their numbers the way they want them and different theories about how horses run.

I'm sure if you used the search facility on this forum, you'd find plenty of threads discussing the topic.

Are you telling me that there is no official method on how winning distances are calculated?

To the best of my knowledge, it is strictly what the race caller estimates. If I am incorrect, I am sure others reading this will correct me.

There is a newer data acquisition system in use at a few race tracks in the USA and Canada that is called TRAKUS. It uses radio signals from devices on each runner during the race. When I am watching a race that employees the system while on track or at an OTB, on the bottom of the track feed showing the race there will be a series of colored dots or squares with the number of the horses. Those dots or squares are showing you the TRAKUS data in near real time. Usually the track feed eventually will show a table of total distances covered by each runner, some of which will be negative values, i.e. that runner covered less distance than the winner.

I mention TRAKUS because the telemetry is collected and becomes data similar to what we are used to here in the USA except in much finer details and, in theory, more accurate. The raw data is for each horses location during the race and is not a relative position to the leader. It is where they are located at any given moment on the race track. And while there are some issues some might have such as the transmitter is not on the horses nose, it does go a long way towards obtaining more accurate information.

Winning distances? There is an official method, but it is a closely guarded secret for some reason by the various photo finish companies.

thanks guys.

I'm amazed that there seems to be no certain answer on this.

As an example (say polytrack in the UK), if the winner of a race beats the runner up by 0.6 seconds it is said to have won by an official distance of three and a half lengths (6* x 0.6 = 3.6 rounded down to 3.5)

*6 lengths per second

Beaten lengths are marked off to facilitate counting on the same film that provides photos to the placing judges. I'm not certain what the time-lapse formula is.

It is the traditional measurement, but I can assure you the photo companies do not equate 1/5 to one length. If a horse is 1 second back at the finish, it is not reported as 5 lengths. Do you disagree?

Let's leave this discussion as the best "traditional" answer to his question is one second is equal to five lengths.

If you know the formula, then give us the answer, what is the official BL conversion. If you know it it is no longer proprietory, unless you paid for the info and signed a non-disclosure.

If you obtained knowledge of the formula any other way, I would be hesitant to admit having it.

I talked to the photo finish company that produces the equipment for some tracks (some Cali tracks, at least)...they told me they use 6 lengths per second for all surfaces, distances, and classes -- that is the factor built into their equipment. So a horse that crosses the wire 1 second later than another would be officially recorded as 6 lengths behind.

I believe I once read Jerry Brown say that he had been given the same information, by someone at Equibase, maybe.

But, I'm not sure I believe them, and other photo finish companies may do something different.

Honestly, how I know it is none of your business. Don't get your feelings hurt because I corrected you. Either believe or don't, I really don't care, but it IS NOT 1/5 = 1 length.

My feelings are not hurt. My answer to you was more of a cautionary tale.

But, you can't tell me my answer about "traditionally" and the DRF is wrong, unless you are willing to disclose the actual formula.

BTW, it is my understanding that it really depends on the shutter speed of the camera, and unless you know the actual shutter speed, you can't correctly calculate the BLs.

it makes more sense to do it like you guys do -- giving a nod to how the fast the horses are actually or likely to be traveling in the final 100 yards. It's hard to believe they aren't doing any kind of adjustment that might move it around between 5 and 6 lengths, depending -- but at least from what they told me, they aren't.

There is nothing really subjective about the finish, while the pace calls are all subjective. At the finish, the formula is set in stone. If you know it, you know the final time of the horse. That said, the formula(s) are flawed, big time.

BL=beaten lengths

The leader hits the 1/4m pole in a 6f race in :45.30....the chart caller estimates (?) the BL of everyone behind him. The time of the leader is all we can be certain of...many anti-pace fig guys bring this up and they are essentially correct, but what else can we go on? The pace call is crucial and we will try to calculate each horses' BL or time or fig no matter how crude it may be to some.

It assumes the velocity of both horses are the same and the velocity of the horses still running to the wire do not change.

Robert Goren
10-21-2010, 04:46 PM
You tell me how fast the film is fed though the photo finish camera and I tell how many seconds each horse is back. Lengths back have nothing to with. I helped a few times run that camera in a quarter horse races in the early 80s. I am pretty sure they use a slower speed on T-breds than on Q-horses, but I am not sure. It sounds confusing until you see it operation.

Robert Goren

There no reason they could not give the exact time for each finisher. They use the basically same equipment in sports like swimming and they give time for each finisher. With the advent of digital cameras this could be done very easily without any additional cost.

Maybe they don't do it because the races would become too predictable? They do it in greyhound racing, but they bump each other in every race anyway. This makes them extremely unpredictable.

They just look at the photograph and approximate it in visual terms.

The real answer is more complex, as the responses suggest, and is not consistent as far as actual time goes.

One of the many little secrets in the game, particularly the U.S. game. The 'Why?' is 'Because it's always been done this way."

No, I tried to make that clear. There are a few that could give you the answer if they chose to do so, but none will. You have to figure it out for yourself. There are also a few different photo finish companies to deal with here, but I think they are all very similar.

There is no difference for distance and/or track condition. You can figure it out. Find horses that are exactly one length, five lengths, and ten lengths behind at the finish. Then, hand time how long it takes them to reach the line after the winner from video. Do this a hundred times or so and you'll have a very reasonable value to use in any calculations.

I have a feeling that it isn't so much secretive as it is just an unknown to most that would normally field such a question. I suspect that the manufacturer uses a default setting that is probably rarely altered by the actual owner upon purchase, i.e. the photo-finish company at that track.

The website for FinishLynx is rather awkward, but there are a few PDFs of documentation, installation material, and technical specs... or you could probably just email FinishLynx and pose the scenario and question and someone would probably give you a better answer than if you actually asked someone at the racetrack level.

Have you ever asked anyone, who actually knows, why split times are not common knowledge over there? Could it be that most of your races are run on grass and therefore splits aren't always that important, in the running of a race?

Turf races, over here at the stretch call, look like 20 people trying to get in an elevator designed for 8. Dirt, however, is different, early pace means much more.

As to your question, I have to use the times I am given, but, I figure my own distance per beaten length, in each fraction, based on the average speed of the leader (the average pace of that fraction). Then I add up all the adjusted fractional times to get the adjusted final time. There may be a better way to figure adjusted final time, according to those who posted that the beaten lengths distance is accomplished via the photo finish camera, I don't know. But, my way works fine for me.

The use of 5 is not because it is exact, but rather the 5 is easier (simple) when calculating., it works.

Many years ago when the one length per one-fifth second rule was established in North America racing, it worked well if nothing more than a convenience, but today with modern technology, the more sophisticated horseplayer, and the advent of the personal computer the calculation need to be more accurate; and there are some people today who are pushing the “envelope” in that direction.

Finally, someone using common sense get's it right! I call it splitting hairs by numbers junkies. I am convinced the number junkies splitting of hairs doesn't mean a damned thing. I'll bet a 1000 races using five lengths and they can bet a 1000 races using their propriatery numbers and there won't be a "diddle squat" bit of difference. Nor will it put them on any greater ROI.

When it is common for horses to win or lose by a nose, don't insult our intelligence by insisting, without any documented proof, that more accurate calculations doesn't make a difference.

Anyone still using 5 lengths per second, or 6 or any other static number, is living in the past. Why even use anything if what you're using is dead wrong?

Sorry for the ranting but this stuff really defies logic.

Raybo, the beaten lengths at the fractions are hardly precise. Why go to all the trouble when your basic data is flawed?

Because I'm a form and pace handicapper, and fractionals are very important, for both. Since all I have for fractionals are position, leader time, and "flawed" beaten lengths, I must use them, flawed or not.

However, if I must use flawed raw data, it behooves me to make all my calculations, on them, as accurate as possible, or, I end up with more grossly flawed data.

This again is getting a bit too technical and not really relevant to my original point (even though it is interesting to see how much you guys rely on times/splits etc).

It's pretty impossible to do it in the UK because all of our tracks are different, from shape, gradient, going etc etc to make it worthwhile.

All I wanted to know was how are official winning distances calculated? From what I've read it seems there is no definitive answer?

It doesn't matter to me how accurate or not the method of calculating it is, just how you do it. As I said if for a particular race in the UK it is measured as 5 lengths per second and a horse wins by 0.5 seconds it will be listed as having won by 2 and 1/2 lengths. Whether that is an accurate way of measuring it is another argument and not important to what I asked. To me it wouldn't matter if you measured winning distances at 1 lps or 10 lps I just wanted to know how you guys did it?

...All I wanted to know was how are official winning distances calculated? From what I've read it seems there is no definitive answer?...

Directly stated: In my experience, the photo finish camera, when capturing an image at the wire begins an internal timer. When the race has completed and the placings are done officially by the judges using the image captured by the photo finish camera - a perpendicular line is "drawn" for every nose in the image and they are sequenced based upon that nose, basically placed from first to last.

At each point at which there is a "placing", there is a time, recorded to the thousandths associated with that placing. The calculation computes the margins from relative finisher to finisher in terms of elapsed time and then also expresses it on the report in terms of lengths, based upon the secret formula for time to lengths, for the benefit primarily of Equibase.

They then may use these placings or may elect to report another value (I'm fairly certain) if in their opinion, the margins are suspect (this is probably most common at mixed breed meets where the margins for quarter horses for example can be plainly flawed when applying the standards used for thoroughbred racing).

Is that to the point and not too terribly confusing?

raybo

I suspect it is secret because nobody wants to divulge an obviously inaccurate formula.

Inaccurate, to say the least.

I checked the Delmar Trakus times and lengths ahead, and, some of the stuff they show is so far from possible I can't imagine they believe it themselves. Just one example was a horse who, presumably, traveled 17 lengths in .6 seconds.

Somebody else figure out the speed required, in miles per hour, I don't want to waste the time, but, it's equivalent to running slightly more than 50 yards in a little over 1/2 second. I know there are some fast horses out there but, whew!!!!!!!!!!! That's movin'!!

raybo
10-30-2010, 03:09 PM
Basically, my times for fractional B/Ls vary from about .14 seconds to around .19 seconds, for open 15,000 claimers.

1/5 second (.20 seconds) doesn't even enter the picture.

1/6 second (.167 seconds) would be a rough average.

raybo
10-30-2010, 03:25 PM
Heck, I might as well finish my point.

If you're using 5 lengths per second (1/5 second per length) and it's really closer to 6 lengths per second (1/6 second per length), you're talking about a whole length (8' to 10') of error. If a horse loses by 3 lengths you're talking about 24' to 30' of error.

Is that ok with you? I would hope not.

I've asked the exact question at 3 different tracks over the yrs, and all 3 at the time used different photo finish equipment and slightly different formulas for calculating beaten lengths.

Sorry if this is repeated , or if this info is outdated and a new change in methodology has been mentioned previously in this thread:


the standard for PHoto Finish Technology (beaten lengths at the finish line) = 0.18 SECONDS per second per beaten length. This is their setting and translates to 5.55feet or so/ length. I don't remember if this was because of working backwards from quarters or what the deal is. (as obviously 5.55 would be a poor estimate) From the info I was given, PFT and similar are the standard in TBred as well. Yet another area that apparently could use an upgrade in tech.:rolleyes: the knowledge is good because it is counter-intuitive


my standard for beaten lengths at calls is 8Feet per beaten length. This is based on the length of the safety rails (which is one chart caller's technique for calling beaten lengths at calls) rather than the intuitive idea of guessing the "average length of the horses from .A-->.B" .

This may be based on 12 seconds per furlong, example:

6f = 3960 feet

6f x 12 seconds = 72 seconds or 720 tenths

3960 feet / 720 tenths = 5.5 or 11 feet per fifth


8f = 5280'

8f x 12 secs = 96 seconds or 960 tenths

5280' / 960 tenths = 5.5 or 11' per fifth

etc.

.18 secs per length would equate to a 1:12 6f time if using 10' per length.

Of course, all of this ignores run-up. That would change things a little.

I wonder why this is such a secretive piece of information? In a culture that posts split times for everything including gallops it seems strange that this info is not freely available?

You rarely get split times for any races in the UK let alone gallops!!

:)

Welp, over there (UK) you have your UK board, while over here (USA) they have the Commissioners for varying States.

It could be ONE regulation, but it's not, much do to the irrrelevance of the real concern.

After running around a mile or so, a length, one second or 1/20 of a second does not give any significance to the outcome.

Aah but it does if you are betting on winning distances ;)

Really? That is news to me, seems like I've seen a few races decided by that or less.

I guess all the winners he sees win by a mile. :rolleyes:

You missed the point.

Two ideas from this post , neither started by myself. One deals with the finish while the other deals with "taking the developed race" and applying those figures to the next race that these horses might enter.




Are you saying the conclusive point at which the race ends for each horse is the offcial order? How true...yep.

I'm talking about "over a distance" during a race, not at the conclusion, the matter of 1/20 or 1 length, has not enough significance to carry that 1/20 or 1 length to the next race that these horses will enter.


Far too many other factors and and and i didnt mean to bring about a turn from the original Post, but other factors were brought into play by others.:)

This has NOT concluded "Race Over". Maybe that helps?
