You're not serious, are you? "The priest answering questions" (whose qualifications in sociometrics or whatever they are call it are --? ) pinpoints it at "25-50%", which you conclude represent "the church's own figures."
Estimates on this have been all over the place (Most -- but not all -- do fall within 25-50%). My own guess would be that the percentage varies widely among various dioceses/orders, and people giving estimates discuss those they're acquainted with. If anyone had any reliable figures (which they don't), the estimates couldn't possibly vary as much as they do.
