Killing my "leeway"

Twas a bad night, with me dropping a buy in almost immediately to remove that leeway I had bragged about just yesterday. In general I loved my table, it had a 40% Saw Flop, so, undaunted, I fastened my seat belt and got ready for the ride. This was the final result:

Table 1 - -40.8bb/100
Table 2 - 8.89bb/100
Table 3 - 23.39bb/100

I still dropped $51, or essentially half a buy in, but considering the roller coaster ride that was going on, it could have been a lot worse or a lot better. I would have kept playing at that table a lot longer, but was getting tired.

I shall leave you with this hand, which I was lost in so badly. :(
