The data is only minimally transformed. I'm not currently adjusting for such changes in regime such as the advent of the NFL 2-point conversion in 1994 or the change in OT rules for NCAAF. I'm basically just following the Stanford Wong methodology, except I equal weight all games that lie the same distance from the target point spread or total.
I plan to improve on the sampling methodology in the very near future. Users retain the option to enter their own probability estimates.

Why not save time and just copy Pinnacle? their data is much more accurate than covers
