How much time do you spend a week playing casual games?

A month ago I started logging how long each player spent in a game, the clock started when the game started (so this does not include time spent in the game lobby) and stopped as soon as they either finished the game, quit or lost. I recorded it down to the nearest second and on a per-game basis. This gives me a very nice stat which I can look at in many different ways, and you know me, I lub teh stats!
