In tournament play (chess) we did have a time limit to complete so many moves in so much time. That way, you could spend more time on more difficult positions, less on the easier ones. Either way, the BBW suggestion or Walter's, it does seem to encourage more rapid play. For me, I don't join many tourneys that are over 5 days per move. I like the fast ones. I'd join more if the time setup was like one of these suggestions below. I've no opinion on which is better tho. Have to think on it.
