Hi all,

Anybody knows why racing post ratings do change after race? I take notes of horses I'm interesting in and when horse is running next time I do check previous ratings and they don't match with my notes every rpr is lower few weeks after than it was on the day of race. So why is that? Thanks

I'm not familiar with ratings but I'd imagine all ratings would change after a race to reflect how a horse ran in that race?

When a handicapper assesses a race that's been run, it's easy to assess the horses in relation to other horses in the race, but assessing the quality of the race and how high to rate the winner is much harder and will not always be precise. After a few of those horses have run again the handicapper will have more information and depending on how well they've performed in subsequent races the handicapper may upgrade or downgrade the original race. This is particularly common in maiden races where there is little previous form to go on.

thanks, is there any way to find out original rpr allocated to horse before race because what I'm interested in is how the horse performed with this rpr not changed afterwards or it just has to be me keeping notes

Contact RP direct..

Your just confusing a predicted rp rating for a future race to there actual rating achecived after the race.

Imo rp rating are the worst rating out there and I never used to think so but OR ratings are far better.

The BHA produce a downloadable list of ratings which I have used when studying ratings

I reckon Timeform are easily the best, they're also statistically adjusted each season but they're not free.
