How bout this... -If you miss weight by 3lbs or more, or you get hospitalized by your weight cut, you're forced up a division immediately. -If you miss weight by 2lbs or less on two occasions, you're forced up a division immediately (giving everyone one allowance for 1 small fuck up). -If you're a champ and you miss weight by any amount, you lose your title on the scales just like in boxing. Your opponent can still win the belt if he/she made weight. If the champ wins the fight, the title is immediately vacated and the ex-champ has to work their way back to a shot. -If you're a champ and your weight cut hospitalizes you, you're automatically stripped and you're forced up a division. I think the big thing is forcing people up a division if they end up in emergency because of a cut. Obviously you're too big for the division (or too unprofessional to be relied on to cut properly) and the UFC can't, in good conscious (lol), let you fight at that weight.
