It may be more efficient to win that amount in an hour than it is to win it in three hours. But if the player does a better job of selecting the right game, he may be more effective, meaning that there is a higher probability of its happening even if it takes him four or five hours a day. That's why I think it's a mistake for some of these players to play as high as they do. It would be much more effective for them to have the win they want if they played in a somewhat lower limit game. It's very important to be effective at what you do.
Efficiency is only good on the margin.
