Hard to answer with the poll it depends on the snake.

This is what I do

For BP up to 100 grams I feed a prey slighty smaller than the girth size every 5 days

For BP up to 400 grams I feed 1 large mouse or a rat pup every 5 days

For BP up to 1000 grams I feed 2 large mice or one small small rat (45 grams) once a week

For BP over 1000 grams I feed 3 to 4 large mice or one small rat (55 to 85 grams) once a week (males are fed on the smaller side)

Works for my snakes.

Note: Prior to breeding season things change a little.
