Data/resources inquiry 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.
