Boxer - what influenced your belief that you don't need as much time off as time on? I'm guessing you're going by personal experience. Do you have any anecdotal evidence that supports your belief? I'd like to come over to the dark side (as it means I'd be happy to squeeze in another cycle this year) but I need to be convinced.

Sigmund - I've come across the 'upregulate' theory before but can't really remember the explanation. Care to expand? I'll do a search too to get myself back up to speed on this theory.
