Please understand that the system is not taking teams -2.5. The system is a set of filters that give me which games to play on. The system wins whether you want to take the team +2.5, +1.5, ML, -1.5 or -2.5. The most profitable is -2.5, even though it of course has the lowest win percentage. It has the best ROI. ROI is my best friend.
How do I feel about taking favorites -1.5 or -2.5?
I've done a lot of research on that kind of thing. There are teams you should always take -1.5 (considering the ROI) and never on the ML, and there are times when you should take them -2.5, and also times to only take them on the ML.
Plays will be posted in a bit, probably in a new thread in order to update the title's record.
