In reply to veteye:
That's my average value, while I was working at Bath Uni I volunteered myself as a guinea pig to help another academic looking into recovery rates using sports drinks with protein in them. I got a host of tests done every few weeks which was mildly interesting (and tedious, why did I say I'd do this again) but what shocked me was during the recovery periods how much you needed to eat/drink to fully achieve this, it was almost mild torture.
More water!! What about recovery beer?
