Last season I used every year to get the percents. After the season was over I went over all the results and tried a few different things. I looked at everything from a 3 year standpoint, 4 year standpoint etc.... The 2 year + the current year had the best results so that's why I ended up going with that for this year. The only seasons that are factored into this years picks are from 2006-2008. Next year I'll use 2007-2009.
I think the problem with using every season was that there was so many games in the database that the percentage wouldn't move very much. Each week would basically be identical.
