I'd figure that around the 90-120 gm range would be fine (if the breeder is as big as I'd guess.) and my rodent supplier calls 70-150 medium rats.
The 10% rule is an opinion started years ago. Sorry but ball pythons do NOT do well on large meals. And those who feed large meals with the mythical 10-15% rule will have snakes going off feed to catch up and come posting why are they not eating.

Ive never had a snake go off feed unless was breeding and even then its slim.

But you feed that 10% rule to them and see how well it works. I couldnt imagine someone feeding a 200-300g rat to a ball python.
