I figured that 1-run games would be more common in this league since the teams are exactly the same. Historical data shows that roughly 25% of all games are decided by 1 run. The percentage is a bit higher for lower caps than higher caps due to lower scoring games at the lower cap levels. So far, 32 out of 96 games (33%) have been decided by 1-run.
My teams are 7-5 overall, but 1-4 in 1-run games.
I'm fairly certain that the individual that compiles the best overall record in the three leagues will be significantly above .500 in 1-run games.
