I had a similar question to this recently. A somewhat agreed number was 200 grams. It was also brought up though that it can not just be one that was overfed because it just may be an obese snake not quite ready to breed. So I would say a 200 gram female that has been fed at a regular rate - being about 1-2 appropriate size food items once every 5-7 days.

It can also very for individuals from what I learn't so 200 grams and growing regularly, not accelerated, is just a rough number and some may need more or less based on the individual.
