John, can you confirm that it's the pressure altitude, not GPS
altitude, that's being displayed and recorded?

It's ALWAYS the pressure altitude that's recorded. The altitude
displayed on the 302 is pressure altitude adjusted for the local
altimeter setting.

So unless there is an accurate source of local pressure nearby, it's
impossible to know precisely how high you are at the end of the day.
