I think many people would understand the following rule to mean that one should stop betting on teams who after the 25th game played have a season-to-date losing road winning percentage:"eliminate teams with losing road records once at least 25 games have been played."Im assuming what you meant to say was, "eliminate teams with losing road records starting with the 26th game and on." Otherwise, it's unclear.
Yes, it's exciting that it has worked out so far.
With respect to RPI, are you now eliminating games in which the opponent is in the top 3 for that week? if so, then we would not make a play on Rangers +1.5 today because they are playing Ducks, right?
