I think that is not a fair comparison. Sure OAA might have 40 - 50 aircraft flying every day. But the vast majority of OAA's flying is training related. Whereas a high percentage of RVAC's flying is by "weekend warriors".
In fact, with the demise of other big operators, Schutts, Combined, Civil etc, my guess is that nowadays the RVAC has a much higher proportion (in relation to the the total number) of recreational flyers than it did in the past.
Perhaps this is where the perceived problem lies.
