There are certainly some in this Certified Flight Recorder Crowd (like
myself, I guess) who think that GPS altitude, properly recorded and
evaluated, should be quite adequate for demonstrating that one has met
the requirements for at least a Gold badge.

You had me convinced otherwise.

That is why it is so necessary to work with the IGC delegates. They are
the only ones who can change the rules...

I guess what I thought was going on here was us discussing whether we
should try to convince the IGC to allow GPS altitude or not. Actually
getting the ICG to change wasn't my focus. If somebody had given a
reason that GPS altitude was just not gonna work, I would drop the
question.
