Let's be clear here. (Yes---I know. You think clarity unimportant.) The AP program *is* "uniformly run". It isn't run by the State of Florida, nor is it run by individual schools or school districts. It's run by the College Board.
Florida evidently has a preparation problem---whether it pertains to teachers, to students, or to both I can't say. But it seems clear that a large fraction of Florida's students who enroll in AP Calculus are not prepared to do so, or that a large fraction of Florida's teachers who teach AP Calculus are not prepared to do so, or that both statements are true. That's a local problem---not a problem with the AP program.
As to your continued complaints that the passing scores for the AP Calculus exams are too low, I suggest that you, yourself, would have grave difficulty in achieving what you think a good score might be on the Free Response portion of the exam if you were to take it, sight-unseen, under the conditions students do so.
