Bris Class & Race Ratings
 

Thought I share these for the benefit of those who don't use Bris pps or those that do & didn't know how they are arrived at or how best to use them
WHAT'S THE DIFFERENCE BETWEEN A "RACE" RATING AND A "CLASS" RATING ?
A RACE RATING measures the overall quality of horses which actually competed in a race - the higher the number, the tougher the competition.
A CLASS RATING measures a horse's actual performance in a race - the higher the number, the better the performance.

WHO CREATES THE RACE & CLASS RATINGS ?
The Race & Class Ratings are generated daily by computers at Bloodstock Research Information Services, Inc.. A Race Rating is calculated for EVERY RACE in North America. And a Class Rating is calculated for EVERY START of all horses in North America.

WHAT IS THE THEORY UNDERLYING THE RACE & CLASS RATINGS?
The Race & Class Ratings are based on the premise that a horse's performance in any given race can be accurately gauged by considering the horses which the individual has beaten; those that have beaten him; and by the margins involved. Final Time is NOT a factor used in calculating the ratings.

HOW ARE THE RACE & CLASS RATINGS CALCULATED ?
Using proprietary computer algorithms, the recent Class Ratings for ALL horses in their recent races are calculated, adjusted and then recalculated every time ANY horse crosses a finish line. This calculation process creates complex inter-relationships among ALL thoroughbred racehorses regardless of the track, distance, surface, or country the horses actually ran at. What makes the Race & Class Ratings such a powerful handicapping tool is the daily updates and constant adjustments made to the ratings which reflect the subsequent performances of ALL horses in EVERY race. The net result of this extensive data crunching is reliable, objective data which can accurately quantify the relative merit of any thoroughbred racehorse's performance.
HOW SHOULD A HANDICAPPER USE THE RACE & CLASS RATINGS ?
The RACE Ratings are excellent tools for identifying which horses have truly been facing the toughest or weakest competition. Like the popular "Key Race" concept but more accurate, the Race Ratings accurately identify "class within class" - that is, they will separate the strong and weak fields of identical race types.

The CLASS Ratings provide a convenient means for comparing the relative merits of each horse's recent races to that of it's competitors. Want to catch more winners? Begin incorporating the BRIS CLASS Ratings into your handicapping. One of the great benefits of using them is you'll spot winning horses which the speed handicappers miss. Look for the horse with the highest recent class ratings. You'll be amazed how many more tickets you'll cash.

Thanks Tim

I will look closer at both the ratings now

Anytime Gene.

Thanks Tim …..the one thing that Bris does not do is calculate a race rating for todays race. TrackMaster does this and it is included in the RDSS screens.

Thanks for pointing that out. Folks are free to use whatever they feel comfortable with. If I remember correctly Doc wasn't that high on TM race ratings. Anyway folks should pay more attention to details that can up their game.

I find RR and CR are very powerful, and even more predictive of winners than their SR. I consider a 2 point deficiency in RR to be very suspect, no matter what the SR>

Also, in the summary section of the Ultimate PPs, they have a column for ACL, average competive level of class.

In my current Aqu model, of 191 races, the ACL rating performed as follows:

#1 24% wins
#1,2 49% wins
#1,2,3 65% wins

Thanks for sharing that info Tom. I also use the current & Acl rankings in the Summary Section. I record them on my form but do not model them.
