Here's a good binomial formula calculator

When I enter the recorded numbers I get the probability 0.0014981776782403485 for only winning 57 out of 123 given an approximative edge of .6 for the average hand(will run this through Pokerstove later).

This isn't any downswing either, its an ongoing trend which seemed even worse before I began this experiment, hence the reason I am doing it.

Maybe a better approximative average edge would be 0.56 which would give he probability 0.019703617603633316, still too low for my liking..
