I have noticed today that I am trying to get a good mix of pitchers together, and even trying to lower percentages, and using levels of unique players, I wind up with X lineups with Pitcher 1 and Pitcher 2, and X lineups with Pitcher 3 and Pitcher 4, and its hard to get 1-3, 1-4, 2-3, 2-4 mixed in there without manually calculating for all 6 different crunches.
