I still can't take a trick at $1/2. Dropped about another 40BBs last night, so had a quick check of my stats so far this month. Overall, i'm showing down less than usual, and winning significantly less than a normal percentage of showdowns. I have to put that down to running pretty cold, rather than any obvious consistently bad plays.
Fortunately though i've made a few BBs at the $4/8 level again to at least maintain my bankroll rather than losing some fairly big chunks. I am about 150BBs down at $1/2 for the month - which would be far far worse if it was at $4/8. Variance can easily do that to you though - I guess that's why they invented bank roll management.
Current bankroll: $19,950
October time played: 4h
October profit / (loss): $50
