I do understand statistics.

Since May 1rst, 2006, My winrate is -1.49 BB/100 over 5138 hands. This is because i played one night and made $60 at $1/$2 but it was on a different computer so i didnt import the hand history. My actual BB/100 is less than this. My SD is 17.8033 BB/100

Before May 1rst my BB/100 is 3.29 BB/100 with a SD of 16.6282 BB/100 over 6029 hands.

Performing a 2-Sample T-Test with an alternate hypothesis that the winrate before does not equal winrate now i get a p-value of 1.160025*10^-47 or approximately zero. t=-14.57546988 with a df of 10614.68117

There is something that went wrong with my game. It is not bad variance
