Hi Bill,

One thing I've noticed is when I use 100% DTV at tracks such as Parx, it brings those extremely aberrant DTV's much closer to the horse's "normal" numbers. The "half" variant, coupled with a tight DTV range, definitely over adjust those extremes. The 100% DTV plus a looser DTV range (you can change it to say +100/-100 in the Config file, the sliders stop at +50/-50) definitely smooth things out. I know that Doc advocated the use of the half variant and had his reasons, but this works for me, and helps me avoid the pitfall of possibly not having a usable line if the next line down is simply not comparable.

In previous discussions with "For The Lead" he does not worry about extreme DTV's, as the program that he uses takes care of the adjustments satisfactorily. If I'm not mistaken, he uses Trackmaster data as well.

As often gets hammered home around here, consistency in methodology/application thereof is important. If people swear by the 50% DTV and tighter DTV ranges universally and they make money selecting lines that are far less skewed, keep doing it.

I'll post my thoughts on this race shortly.
