At what point do you stop?

No I don't at that size they get 55/65 grams rats.

I feed once a week

The 10% -15% of their weight "guideline" is something I never used, I just eyeball it.

While growing BP need more food as they get older their metabolism slows down and do not require large amount of food to strive.

Smaller preys weekly are preferable to larger preys.

I could not imagine feeding 450 grams rats to my 3000 grams girls and obviously if they reach 3000 grams with my feeding method they are far from starving .

Smaller prey also allow a BP to eat with more consistency with less fasting period.

I agree with Deb 100% I feed all my adults 1 small rat once a week. Since i do not breed my own rats if someone does not eat their small rat someone else might get 2 small rats that week but it is not the same snake and does not happen often.
