I wouldn't try to compare and go as far as saying worse graph, but this is my graph for cash since 2009 - essentially 14 Years of running below EV in cash on every stake all the way to $25/$50.
No, it would definitely explain the all-in ev gap. If you are constantly getting it in when your opponents outs are super live then the all-in ev metrics will all get screwed up.
Another thing OP, running below ev doesn't "make" you dump money on sports betting. You are just a gambling addict.
you probably never had a proper doom switch or you are not a winning player. As a winning player I don't mean barely above 0.
