I've always heard it the other way. Back it off during the hunting season since you are not taking so many shots and most hunters don't practice at all during the season. I have heard for indoor leagues to back off the draw weight for say 20 yd. 300 rounds. I personally keep the draw weight the same unless I really shoot a lot and can hold more comfortably. During the hunting season I always pull the bow back first thing in the stand and several times if I am bored and not risking spooking anything to "pump me up".
