Sure this is based on OLC-uploaded flights only, but still any
statistics is based on sampling and OLC to me is a quite reliable and

Cool!

But how did you manage to download 14000 flights from OLC? I thought
they had "data mining" restrictions, or have these been relaxed?

Of more interest to me if I were buying a glider is the average hours
flown per year since new for the mark. If you come across a glider that
is either tricky to fly, tricky to maintain, or just not that much fun
to fly, it is likely to have lower hours. Your average K21 is likely to
have flown a lot...
