I fail to see what you are trying to prove here.
What is to be gained by establishing some kind of average value for these parameters?
As I have said, there is a wide range of flying going on, and working out an average is meaningless.
If anything it would be utterly depressing. I mean, how long do you think it will be before a 15 hour/year pilot renting the typical piece of flying scrap metal is going to say to himself (literally or subconsciously) :
"this hobby is such a huge hassle, it costs me so much money to do the 15hrs, I get so little in return for it, I have such poor currency that I can't go anywhere, nobody but absolute anoraks wants to fly with me in the piece of crap that I can get, a lot of people politely refuse to fly with me because they are horrified at going up with a 15hr pilot (**), there is close to zero crumpet hanging around this scene AND/OR my wife/gf can't see the point of me doing this since I never take her anywhere nice... I might just chuck it in and put the £1500 towards an upmarket gym membership and an upmarket tennis club membership (both of which will provide much better scenery)"
??
One has to be positive to move forward in this (or any other) business. Yes most PPLs fly few hours and are as tight as the proverbial but if one believes that will never change, where will that get us? Light/Permit aircraft is a good answer for many but the ownership costs are perhaps half of CofA and that isn't enough of a difference to make a big difference, in a game that requires this much long term commitment. The key is in improving what people get out of it. If the "scene" is crap (like it is in so many respects) then even £5/hour flying won't interest very many.
