You can't answer that question. It would be like asking how fat should all humans be? Can't be answered. Each snake is an individual. I had a female that was the fattest snake you'd ever want to see. She was every 6-7 days, but she was always a fat little thing. Ive got a male pinstripe I rescued, that won't fatten up no matter how much I feed him and he's more than 3 years old.

Just my opinion,
