Yes of weight, yes it does, it is hard to feed an adult snake enough mice. My adult males are averaging 1600gm the biggest mice I can get are in the 35gm area a full meal would be 4-5 per feeding I usually feed adults lighter than this but still 7% per week so that is still 3-4 extra jumbo mice.
I have a suspicion that you male is quite small for his age, that is just a guess on my part.
