For the record, I suspect my play deteriorates much more quickly, in a sense. I still usually single-table because I'm not that confident yet. And if I lose 50 bb, I definitely start getting frustrated. As much as I think I'm controlling my emotions, it probably does affect my play at that point.

Playing one table can have a psychological effect on anyone. You're very conscious of how much you're up or down. Winning isn't such a big deal, but losing can take a toll on you. It's much harder to "get even" when 1-tabling, and sometimes we tend to force certain hands out of pure boredom.
