To clarify, the final riding position between a rider with flexibility issues and someone who does their homework when it comes to stretching will be different, but how we arrive at those positions will be through a similar process. You are absolutely right when it comes to the number of fitters regularly fitting pros. In my experience (and probably that of every fitter) is that most bike fits are done with "average" riders, not "pros". I also agree that for most recreational riders there should be minimal regard to being aero, and again, this will be for a large number of fits on novice riders. The question should always be "what are the specific outcomes regarding position on the bike for this rider".
