AbigailII: "With ../0.6/.., if you sleep 7 hours a day, and be online the other 17 hours, you still may lose the game on the clock. It all depends on when your opponent moves - which is outside of your control."

I've been thinking about that for an hour now, and I don't think it's true. Remember that every time you move less than 6 hours after your opponent, you gain time. If you're online for an unlikely 17 hours a day, two things could happen:

1. Your opponent makes moves during the day. If you respond quickly (i.e. in less than 5 hours!) the time you save will more than make up for the time you lose during the night.

2. Your opponent doesn't move until you log off. When you log in the next morning your clock has been ticking for 7 hours, so in this case it's true that you lose 1 hour. But meanwhile, your opponent has lost 11 hours because he didn't move all day. If this goes on for several days, he'll time out long before you do.

In general, if you're able to log on four times a day and there's more than 12 hours between the first and the last log on, I think this reasoning applies. You can't possible lose on time, because you'll either make four moves a day or play faster than your opponent.
