Statements about recovery rates, which are actually numbers, need some supporting evidence to be believed. Personal experience stands on its own and is valid for itself, but in no way supports this sort of stuff. No one can argue with personal experience, but it is no more than that. It is a single point, not a rate, not a number. It is not 'data'.
There is data about recovery rates, lots of it, all anyone has to do is look for it. It was an eye opener for me to do just that, others might be surprised too.
