stats not calculating correctly

no idea what this bug is but heres a pic, as you can see BB/hour is way off at 5 and 10NL...I think somethings gone wrong with it calculating hours and its throwing everything out?

EDIT can I also comment that only allowing an image 800 wide is really bad if people intend to give you screens of PT which is much wider than that? hopefully you can still work out what I'm talking about on the cropped lower than 800 image.
