I prefer ( when of sound mind) not heavy medicated

to pick the best TPR rating from the last 3 comparable races starting with line 1
But now I am forced to use the best of last three speed ratings or now perceptor and not go back more than 4 lines
My ROi and hit rate is the same what ever way I use
Doc's advice is to use the best speed rating of the last 3 or 4 when a
non comparable line is one of the first 3 lines
He write in the very same follow up (81)
That he will go to the 3rd line when a horses last two races are not useable
because of bad efforts But he shows no example
What FTL is teaching is if the last line is not one of the horse best efforts
in perceptor, or high speed rating It should will always have a valid excuse
If it does not have a valid excuse than that horse is a non contender
(in most races )
from the Doc.
