Well, partly. CH, I've also been using something similar to what you are talking about for the last 1 1/2 year with much success. HOWEVER, Jerry is right when he says there are really no to qualtify this "effort" and he just gives you accurate # and you can adjust them as you see. Also, just becuase a horse dueled inside means he should have earned a better figure. There could have been a rail bias that carried him along( I think this was present at FG on LA Derby day). So you have to make a qualitative adjustment not a quantitative adjustment. Also, if there was no rail bias, then the fig. is actually much better than give n but this horse may bounce next time, so as in all races you have to play the odds.
In regards to comments such as horse won easily, was all out, tank empty- in my experience this is all NONSENSE. I would just depend on the pattern of the horses and not these old time comments. I know a handicappper in SCAL who publishes these things and they are invariably wrong!!
Just adding gas to the fire!!!
