OK, I'll buy that. My interpretation of the original post was that
since the GPS altitude showed him lower than the altimeter, he could
go up higher before entering Class A airspace (18000ft - I stand
corrected). That interpretation would be incorrect, for all the
reasons we both have stated.

I didn't write that I saw GPS altitude less than the altimeter. I wrote
that it was higher.

GPS altitude is NEVER less than the barometric altimeter set to a local
altimeter setting - at least in my experience.

You are absolutely correct, I went back and reread the original post
and realize my mistake. So we are all in agreement after all.

Bottom line - Altimeters for airspace, GPS for glides!
