Why would a player be better at MTT than STT?

[schwah]

fyi to get some idea of what your winrate is you'll need to play something like 1-2k stts or 5-10k mtts

even then its possible to run quite a bit below or above expectation. my lifetime roi in sngs is around 12% but ive had a 1k+ game losing streak. and variance in mtts is waaaay worse.

400 stts or whatever is close to meaningless and 90 mtts is meaningless
