you can assume D+ to B is 100% without being too far off. D+ to B could be 4 partial grades (1 and 1/3 full grades), or 6 partial grades (2 full grades), depending on if its a high or low D+/B. so there is a pretty big range there, from best case to worst case. using exactly 5 partial grades, the D+ school is going to have to put in almost exactly double to break even.
