Fairmount,
I'm sorry I don't have time to do the Graded analysis like you suggested. I did a quick 4 year olds and up for Pletcher, all sprints, routes, turf, etc., for the following tracks since 2009.
GP 419 starts/120 wins 29%
KEE 87 starts/24 wins 28%
AQU 343 starts/88 wins 26%
SAR 182 starts/42 wins 23%
BEL 270 starts/52 wins 19%
CD 97 starts/7 wins 7%
Because this is for all his races with 4 year olds and up it is very non-specific as to quality of horse/distance/surface/intent, etc.
But, if you look at the above numbers, you just gotta ask yourself, "which number looks out of line?"
