That's sounds like a good one. Easy to understand and work with too. My average idea would take awhile to get the feel for. The grace period and the total time are easy to adjust and see. I suppose in a side game the players could agree to put more time on the clock, or take it off too. I hadn't given it much thought since the timing system here is like the one IYT uses. I imagine there's probably lots of ways that have been tried or thought up. I'm all for giving the players in side games, or the tournament director in tournaments more options.

As for your sadness mrloupcity, I think it comes from misinterpretted intentions. Some people see the time limits as a restriction and others see them as an opportunity. Other time limit systems can change the balance and make for more or less problems depending on the individuals involved. It'd be nice if there was a speed rating or moves per day average for each player. Then a player or tournament director could also set a range if they desired, simular to the rating range to allow a particular speed of player enter a tournament. Instead of just fast tournaments, one could also set up a slower paced one too.

I'll stay out in the middle of the room. :)
