Totally wrong. A 300bb downswing is ridiculous when playing well. It just doesn't happen as often as people are saying. Put it this way...if you put in 4 bets every round and lost you would have to lose well over 20 hands to get to 300bb.

I would wager most people who convince themselves a 300bb downswing is normal are somewhat competent players in games too tough for them to handle comfortably.
