bankroll calculator on VPW

[treeson]

I use the bankroll calculator a lot on VPW, but based on my results I think there is either something wrong with it or I am interpreting the results wrong, because according to it id be running like 4 standard deviations below EV.

I am assuming I am mistaken and not the software, but I was just wondering if there was anyone knowledgeable about the bankroll calculator and can tell me if they know for sure its accurate and I just am in fact running really bad.
