lol cmon bro. If you think All-in EV EV doesn't have much to do with ur winate, ur clueless . In today's game, **** ton of money goes in on coinflip situations PF or on the flop. If you're constantly on the other end of the flip, your winrate will not be good as others.
Look at this graph for instance. It's a graph of legendary grinder of our time. Ya, sure he'd still be winning a **** ton even without all the flips he won but it's a indicator that all-in EV has major impact on ur winrate.
This is graph of whatever hands I bought in my database for 2010. What's crazy is friend of mine sent me a datamined graph of him being up over 6digits in ev last yr. I would not be surprised if he was up atleast 300k+ ev in his life time. Some ppl always ran good and will run good forever. That's not poker. That's life.
