Here is a link to the thread I ran last year:
http://www.sportsbookreview.com/forum/nfl-handic...-modified.html
The stats from 2010 are as follows:
JM System: 9-0 official, 10-0 unofficial (+9/+10 units depending if you played Detroit)
Modified on3 system: 8-1 (+.3 units)
I had also introduced a LWL .500 system that did not involve a chase and went 8-4 SU last year for 67%.
I will be updating this thread once the season rolls around.
