Interesting concept and interesting formula. You didn't specify a database so I used STD and got 23-7, 76.7%, for +15.3 units to date on totals. Not bad, and it recommends 4 games for this Sunday.
I doubt that I could build a formula as bad as the three I already have. One is HIROLLER which was created by Microbro and was part of last years software. Modified to STD it is cruising along at 16.7 %. The other two are X and XBUG which I copied from the forum last year. X was created by Nevess and XBUG by Nevess as tweaked by Bugsy. X is currently at 3-14, and 17.6%. while XBUG is 3-16, and 15.8%.
Strangely, these were two of my best formulas last year. Through the middle of October, 97 they were both over 90%. I have never really had a formula that stood the test of time over more than a couple of years, but to go from the best to the worst in one year is ridiculous. Keep up the good work. Dave
