Ah, the infamous "program letter." My suggestion would be to talk to
the kinds of people who routinely file program letters and have no
problems with them at all: competition sailplane pilots. There are
probably more than a thousand European competition sailplanes in the US
being operated on Experimental/Exhibition or Experimental/Racing
certificates, and I've heard of very few complaints about their
operating limitations or program letters.

I think that the most common approach is to include on the program
letter any contest or event that you might possibly attend, and then
add some extra verbiage about proficiency flights.

If you search rec.aviation.soaring on the phrase "program letter"
you'll find a lot of general advice, but probably few concrete examples
of complete program letters.

Thanks, and best regards to all
