If you look at above pic its missing block 29011 which bsod got. But it didnt register til 20-30 mintues later. And say if you were doing 100gh/s for example during block 29010 til 29013. But when block 29011 gets paid out thirty minutes later and youre at 1gh/s, you get paid on the 1gh/s. I hope you can understand what im saying.
