thanks for doing that research. i think this system has some weight to it, and if you can play the -1 RL and have better payouts on your wins, even though you are having more pushes, I would expect you come out ahead in the end of the year compared to just playing the ML. Because as we know, most of the good teams (NYY, BOS, PHL, LAD) can put up runs at home...very interested to see how these numbers come out after you crunch them!
also, like someone mentioned above, you are wanted to back great home teams, but also teams with solid starting pitchers. so if a team was solid last year at home, and there has been some changes in the rotation, or a SP may be hurt, it may be wise to hold the team on the sideline. but a team like the SOX this year should be beautiful in this type of setup with them having 3 aces potenitally. also, another sleeper team to watch is the Diamondbacks. If Webb comes back healthy, with Webb, Haren, and Jackson, you have 3 aces on that staff as well.
