Only value I find in motorsport is in matchups, and base those on a combination of past driver form at track, past car/engine form at track, and current season / last 5 races performance..
I do F1, may try some limited capping of NASCAR this year as time allows.
If you bet NASCAR then you are smoking better stuff than I am!! Cap
this and waste time. Ask you girlfriend or boyfriend who they like
thats a more efficent and profitable way to win..
