How much is winrate affected by how long a session you can play?

This is only somewhat related to the OP, but I think it ties in. I play generally at two times, early afternoon (Midwest 11:30-2:30ish) and early evening (midwest 8:30-11:30ish) and I have found that my winrate is much larger (and +) in the early afternoon and much less (break even or -) in the evening. Granted, it is also when Europeans vs Americans are playing, as well as other factors, but the single most significant factor I think is that I am relatively sharp in the afternoon but ass tired by evening. I am not getting much sleep and what I get is interrupted 2-5 times a night (my young’ems sleep like shit, if you think you can do a better job I will ship them out to you).

So longer sessions probably do mean higher winrate, but only if you can maintain the sharpness of mind and quality of thought that you (should) have earlier in sessions.

I don’t know much about him and I am not a fanboy, but from what I have heard that is one of the reasons that sbrugby rose so fast. He could play these marathon sessions without any (noticeable) drop in focus.
