Do you mean "Have ever run to today's par?"

I like this idea.

I am aware of no such tool, but it could be accomplished with some code in my future software - target for release is a few weeks away.

Quick Grid has a count of races at or above par minus 5. It is on the Speed Deep Dive grid. It is a comparison to BRIS pars, not raw times. Quick Grid uses BRIS data files (single file or Multicaps).

Yep, any running line at all for any horse that happened to run close to both 4F and Final par. I'm looking for discrepancies in different sites' figures.

2 random horses from 2 different tracks both running to that particular tracks' 4F/Final par (as well as similar TV) should yield similar figures. However, there seems to spots where they don't. I want to see if measuring this theoretical margin of error and adjusting for it yields an edge over other users of those particular figures. Possibly a lot of work for nothing but I have time so oh well...

Dave/Dustin, I believe Dave uses a rating he calculates for each race which is based on running lines for entrants. I don't recall the specific name for the rating. In short, the rating represents a PAR for each race based on entrants instead of race conditions. For example, we've all seen $10,000 claiming races that appear much weaker or stronger than an 'average' race.
This rating may be an alternative to PAR yielding better results.

Tony is correct.
The challenge is that a $16k claiming race may really be anything from a $10 to a $25k race. Usually plus/minus 2 levels.

That's why I recommend using a strength of race rating instead of par.

My new software is really getting closer now.
It will blow your mind with stuff just like what you're talking about.

I guarantee that you've seen nothing even approaching it before.

Stay tuned.

That is the rating Dave, thank you.

Just a short comment about what is being discussed here, quite some time ago I created an "Object" with 6 appropriate "strength" factors which I applied only against my contenders it proved out to be VERY strong in pointing to the Best contender.
