Renton,

I've had similar slumps after reading HOH 2.

I only play $5.00 and $10.00 SitnGos on pokerstars and I think the slumps were caused by experimenting with all-in vigorish and pushing too much in the late stages.

I think all-in vigorish is useless in these SitnGos because there is a high probability of getting called. Pushing with sub premium hands (like A-x or pocket pairs) is something which took me longer to realize. I now consider myself lucky if I get away with it once in a game - and my results are improving again.
