But wait….haven't you lived off of that money for the last year? So you can't say your bankroll hasn't grown. It grew, but you used that money for living expenses. That is sort of the way it is supposed to work.
I don't know what your living expenses are, nor your projected EV, nor how many hours you are playing. Perhaps some of those need to be adjusted , like playing more hours to cover your expenses, but I don't think you have proven this doesn't work, I think you have proven just the opposite and don't even realize it.
