Anything Better than APV or EPS for a Class Rating? I'm a firm believer in form cycles. In fact when I project a figure for a horse I almost always project improvement or regression from the last effort. Past races, some fairly old, are the basis for my projections. I often give more credit for a race from 4-6 months than I might the last 2-3 races. That's why I'm having trouble agreeing to time decay when it comes to speed and pace ratings. — Tony Kofalt
Tony, I agree on time decay. Many of today's trainers have solid intent first off a long layoff, as evidenced by their high win percentages. And, I, too, am willing to go well back into the running lines to find a race that might correspond to today's race. For instance, turf route lines tell me little about what will happen in today's dirt sprint. In fact, I've come to consider selecting a "pace line" as one of the most important aspects of handicapping. And that certainly is contrary to time decay. — RanchWest
I am saying that STATISTICALLY (i.e. as a metric) time decay produces FAR better results than something like (say) BEST-OF-LAST-2.
If one is choosing a PACELINE - especially a single running line, that is a different solution to a different problem.
In that scenario, picking the race that the horse will run today will either be good or bad - based upon the skill of the picker.
One approach is for a SYSTEMATIC approach, the other ARTFUL.
I do not see how the two can be compared.
Do you guys?
