Thank you so much for these. I will put them into my research for this project, but after reading a bit into the one about set depth I am realizing maybe I should just altar the way I am going about this entirely. Instead of having a couple features that can't be narrowed down to a value between 0 and 1 I think I'll just start working with what can be averaged like that to simplify things. So if I were to do this and also use a game-by-game timeline for recurrence rather than a day-by-day which would include multiple games, then that should eliminate my need to do variable size sets for now. I will try implementing that later... so now my only concern is how to order each game, because since games can be played on the same day and statistic websites don't log a record of exact time start, how would I decide which order the games go in for recurrence? Or would it not even matter? Sorry for tossing even more questions at you but I figured this is an easy one for you.
