How about -300 BBs in ~2500 hands followed by +425 BBs in ~4000 hands? Defintiely my most extreme ups & downs that I can remember.

Hi Catt,

That looks roughly like -11BB/100 followed by +11BB/100. Thats a dramatic difference. How about showing us two General Info. Tab screenshots, one for the first period and one for the second. It would be interesting to see if you were playing substantially different in those two periods or not. Did you consciously change anything in your game?
