Heh, I took a 225BB downswing when I moved up to 2/4. It sent me back to to 0.50/1 with my tail between my legs. Reviewing the period carefully in PT revealed a combination of some really awful cards coupled with a few mistakes in betting strategy that magnified the effect of the bad cards. It was frustrating as hell, but it's nice to know that at least I bought an education for my cash.
