BRISNET Past Performances beyond 1 1/8
Many years ago when I started using BRISNET PPs among other past performance data sources I printed out how they should be used and I was especially focused upon the pace figures fully recognizing they are machine-generated. The current instructions do not say this. I even spoke to one of the public handicappers at CDI about this and they had no idea either way. When I say comparable I mean speed figure wise for sure.
The instructions on their use as I recall, clearly stated that they were not comparable beyond a mile and one-eighth. I am doing this by recall and through moving I lost the printout. As I recall, the printout stated they were good to compare to distances up to 1 1/8 and they may have even stated they were not useful below five furlongs in terms of comparability.
I have gone by that assumption for quite a period of time and have concluded that they naturally rise above the distance on both dirt and turf. It is an assumption without a database build of any robust detail. They even seem to go up with TimeformUS based upon my non-database observations.
Does anyone have any data on this natural change with runners to prove or disprove this theory. It would have to be enough prior starts for runners individually and in total to see. It has helped me find runners going long mostly on turf because of the natural pace being typically slower in my view.
