The issue was about the 50% win rate, not ITM.
Stephanicov, your chart at 4 1st place wins out of 24, is about a 16.667% percent win rate. I sort of consider that a HUGE difference. We see here you are doing a bit better than 50% ITM, which is fabulous. Hope you haven't jinxed yourself now for posting that same chart twice in one week!
The notion was put forward as a project, so no claims have been made as yet. 50% ITM would suit me fine.
It goes on to suggest a min of 25% win rate, which I believe will still make money if you never got any other ITM spots.
The idea of the project may not be winning % anyway. It may be more to get folks thinking about BR management.
At the present my BR management plan is 'If I don't feel right, I won't play".
