How Much Should You Win?

There is something out there called the law of diminishing returns. While this particular law generally refers to resource allocation and productivity, the words can apply to somebody sitting at a poker table. Winning is not a constant state, and for a lot of people their best poker is played during the first few hours of a session. Just like the least amount of work gets done on Friday at businesses across the planet, or near 5:00 pm on any standard work day, the longer a player stays in a game, the more the quality of their play will degrade.
