TrackMaster Race Class (RC)

Q: What is the Trackmaster RC (Race Dlass )? Can we used this with race RC ranking of the race with RC class for the horse?
How reliable is this indicator?


A: The RC number - Race Class - is supplied by TrackMaster, and is integrally related to their Speed Rating, Pace Rating and by extension, their Daily Track Variant and Inter Track Variant. In other words - every final time related number they create.

Dave Siegel, president of TrackMaster explained Race Class (RC) to me once, but it has faded enough that I should let him explain it himself - which he does in the 37 minute video below.

Essentially - RC is the product of the composite of the most recent final time Speed Ratings of all the horses in the race. Sometimes the RC number for the race (e.g. in the Result Charts or in subsequent Past Performances) will change when horses are scratched - which makes sense for a number derived solely from the final times of the entrants - and not the man-made class levels such as Claiming, Allowance, etc (which might more properly be termed Race Conditions, not Race Class).

When you think about this, it's not surprising that RC numbers derived solely from final times do not strictly match Race Condition levels: final times are at the mercy of so many things including weather, the particular track involved - but probably most of all - the matchup of horses running in any given race (i.e. slow pace, fast close; multiple early runners and a torrid pace - slow close; paceless races etc, etc).

Like any given set of Speed Ratings (e.g. TrackMaster's, BRIS', RDSS' internal Adjusted SRs) - they may differ from each other but they will all be coherent within themselves because each of them uses a consistent (if different) concept and formula. So TrackMaster's Race Class number may not co-relate with Race Conditions, but it measures on a consistent basis at least the recent Final Times of the horses involved in each race.

After all - no one is surprised that any given Claiming $20,000 race at the same track, even on the same day, may run in remarkably different final times.

FWIW, I make almost no use of RC myself, and really have no advice about how best to employ it.

Anyway, here's Dave Siegel. It' fascinating if you can bear with it ...
