Hi guys,

I talk online to a lot of people and yesterday I had a conversation with a guy who showed me 2 pages of math to determine the "perfect" size for a 4bet when he plans to 4bet/fold. He assumed a 3.5BB openraise, a 10.5BB 3bet and some x.x% ranges. Personally, I think this is nonsense. 3bet sizes vary (I consider 10.5BB too small), ranges vary (he had non-polarized, unreal ranges) etc.
Now, when watching videos like unconventional wisdom there's vanessa, one of the biggest winners I suppose, saying "I'm gonna 4bet to like, umm, 56 or 54, doesn't matter all that much." And I think she's right, those differences in 4bet sizing improve your edge by 0.x%. Is it really worth the time making those calculations? imo there are a lot of spots which are more critical to winrates and need to be focused on instead of some 4bet sizing. What do you guys think? Im just wondering if I am actually missing something by not doing that wizard math things...

no, they are doing it in theory sessions, not while playing
