300 moves per day. Assume 30 seconds thinking time (Which is quick in my book). That is still 2.5 hours / day, which seems excessive.

I agree with tracking "How long do I take to move".

Also I absolutely don't see the point in playing so many games. It seems to me that a game is enjoyable when you can follow the flow of the game as it's happening rather than waiting weeks to play a move. Even if I could play 300 moves, I'd want to play 10 moves in 30 games, not 1 move in 300.

Just my 2c :)
