And that's exactly the problem. *Because people find your airspace
files on TP exchange they think they have some "official" status.
they then get to a contest and find the scorer's airspace database
come from a completely different source. Maybe some contest pilots are
not even aware of the issue and won't be until a database difference
costs them a contest day.

I'm not criticizing you Lynn, you are doing a great job of providing a
set of data and John is doing a great job of making it available.
However, contest pilots need to know what database will be used by the
scorer and that exact database needs to be available to all pilots
before the contest starts.

Most scorers are aware of this, and use John Leibacher's site to
distribute turnpoint and airspace files that they will use during a
contest. They have figured out this saves a long night of pilots lined
up to download files from the scoring computer, complain about
different file formats, and so on.

A big effort to have one "official" airspace file for all US contests
seems like a bad idea, and the current system seems to work pretty
well. Airspace files need to be updated; many computers can't handle
very large files (entire US); contest officials have the right to
impose their own airspace restrictions, and sometimes (by waiver)
remove airspace restrictions; many pilots like to edit airspace files
for a contest to remove all the clutter that doesn't cost points (moa,
parachutes, etc).
