For the past few years I've been auto-generating stats by scoring sql query results for rider, trainer, sire, damssire, post position, etc. given today's race attributes (Track Code, Surface, Distance, Fieldsize, etc.)
For riders, it doesn't matter if the race being scored is run at (say) Remington Park where riders use the whip as they see fit or at (say) Monmouth where limited whip use rules are enforced.
The stats reflect a combination of each rider's historical wins, 2nds, 3rds, 4ths, 5ths, etc. adjusted for field size and number of occurrences in the data.
True, there was an initial period of noise in the data when new whip rules were introduced at both Monmouth and Santa Anita.
But after the first few weeks at each venue the stats auto adjusted quite smoothly (all things considered.)
In other words the riders adjusted to the rules in place where they ride, and the stats reflect each rider's historical performance good or bad.
