Pounds Per Length/second

[mwilding1981]

I am trying to work out how to calculate a few things and am struggling and was hoping for some help if possible.

How many pounds equal a length at a particular course/race type and distance for good going

How many pounds equal a length when the going has changed

How many pounds equal one second at a particular course/race type and distance.

Thanks

Someone somewhere will have the exact answer to this.
Having said that, in sprints I ignore weight altogether.
The farther a horse goes weight will have some meaning.
I seldom include it as a factor, and if I do, and no pun intended,
I give it "little weight" in my thinking as to who will win.

As Quirin pointed out, it is usually the case that high-weighted horses meet the conditions of the race and are therefore at an advantage and win accordingly.

So, it is difficult to correlate weight and speed.

Try a search for that here - there was a thread on this a while ago that might be just what you are looking for.

At one time, It was generally considered to be: in a sprint 3 lbs equaled a 1/5 of a second equaled a length. in a route 2 lbs equaled length equaled 1/5 of second. Today Weight is generally ignored.

Can't remember where I heard it, but I think it was 5 pounds equals one length at one mile.

As far as how much the weight effect changes given a certain track condition, I really don't know - that would be highly track specific and you'd have to look at mountains of data/track variants/etc. to figure it out.

Weight has been statistically debunked for a long time now. Quirin's Winning at the Races: Computer Discoveries in Thoroughbred Handicapping is a prime source of rational statistical proof from thousands of contests.

Weight can and does slow horses down. Pile enough weight on the back of a horse and eventually he won't move. Of course, this does not actually happen but it explains quite simply that weight does slow a horse down. 2.4lbs would slow a horse by 1/5 second every mile it runs. That would relate more to speed figures. A rough guide to answer your quesion would be as follows:

Distance Pounds per Length
5f (1000m) 3
6f (1200m) 2.5
7f-9f(1400-188m) 2
10-12f (2000-2400m) 1.5
12f (2400 plus) 1

The puzzle that you are attempting to solve is the kinetic energy of a racehorse.

Therefore from physics we understand that kinetic energy is the energy possessed by a body because of its motion, equal to one half the mass of the body times the square of its speed or simply the energy of motion of a body equal to the work it would do if it were brought to rest

In applying that to a racehorse you need to know the value of certain variables which are the weight of the horse, the load toted, and the velocity run by the racehorse. Also it would be best if you use final velocity for the distance in question.

This is a non-trivia calculation and would get away from the forum’s intent because it is physics, but if you search out the variables you can calculate a very good and reliable result.

Even if there were a demonstrable effect, HORSES ARE INDIVIDUALS, not subject to what Leonard Mlodinow calls the "psychological illusions that cause us to misjudge the world around us" in reference to things gleaned from a database.

Do not utilize a database: specificity is lost. Gave them up ages ago. Talking about a basic difference of style and sample error. Beyond that read into it what you will.

IMO: Weight categorically cannot be “meaningless”. If an animal is asked to run with a refrigerator on its back (plug in the rider you like to bash most here) vs. another of “equal” ability with a feather; the refrigerator cannot possibly help.

The top weighted animals are normally the top contenders in the field thus distorting most attempts to quantify it. It’s not “if” weight is a factor, it’s to what degree and is it possible to accurately measure the impact of X lbs and most of all...make money with it.

Contrary to the sheet maker’s belief in their adjustments there is massive “noise” in calculating the effect of weight…including dead weight vs. live and the size of the animal carry the impost.

BTW: A search of ‘Cratos’ on this subject will yield some very smart discussions if anyone interested.

I fail to read many things…the post responded to what was quoted.
