Last night, I did a quick check of the past season of NCAA Football and, unofficially, ended up 40-0 when using a 6 game chase. There was only one 5 game losing streak in the beginning of November (I think). Everything else looked good. No worse than an occasional 3 game losing streak. Not bad, considering you're dealing with -110 lines. I used the closing numbers at scoresandodds.com.
While doing that, I was randomly checking other sports, like the CFL and WNBA, and those looked promising as well. It's strange, but if it works, what the hell.
