Also stop if the series ends without a win.
I did some due diligence on this system from last year and can pass it along if you wish. The main thing I found (as I have noted in other threads) is that you need to avoid the worst teams. Last season the teams that were .500 or better on the season were +220 (estimate) units and the teams under .500 were -216 units. Thus, the system was about +4 units.
HOWEVER, the 7 worst teams in the league (all of which were .450 winning % or worse) accounted for 210 of the 216 units lost from the under .500 teams. THUS, if you can identify those teams and avoid them, this system should work great. I am playing the same system and posting my plays. However, I am avoiding FLA, KC, TB, Wash and Pitts and playing the home team at -1.5 when they are on the road. I am deviating from SSI in that regard and hope he joins me soon.
Wash and KC were on the road this weekend. Wash lost by 2 the first game and won game 3 by two, thus winning and closing its series. KC lost all 3 games for a -700 but I had TB (played KC) and closed them in game 1.
I have it all on a spreadsheet if you are interested in seeing it. I also looked at runs scored, runs allowed and run differential to see what the best indicator of success was and winning percentage was the best.
