College Board's Transition from Physics B AP to Physics 1/2 AP an Epic Failure?

Test Preparation AP Sciences
32

I think its also worthy to note the percentage points needed to get certain scores (obtained by @skieurope 's link)

AP PHYSICS 1 GRADE Percentage of available points on the test
5 71%
4 55%
3 41%
2 26%

I got the impression that many (including my own) teachers believed the cutoffs for these scores were going to much lower. I know my teacher, in constant contact with other AP 1 teachers, believed 25% would be good enough for a 3 (and a 5 would be ~63%).
Do you think CB made the curve too harsh? I believe AP B’s cutoffs were less harsh for a supposed easier test.
