Bad Called River Bet graph?
So I noticed sometime ago that I have a pretty negative Called River Bet graph. It goes like -$80 in NL2 zoom I think( in around 100k hand), but I'm not sure because I don't have access to my database right now. Is it ok to have a negative graph like this for this filter? Or is it a major leak in my game? I do think I call more Rivers than I should and I am trying to improve that, but the graph is scary to me and I don't know what to think about it. So, do you guys have a positive Called River Bet graph?
