We could also get real and eliminate the pressure sensor out of the
logger and start using geometric altitudes like the rest of aviation.

Which would make it really easy to fake a flight using a GPS simulator. The
change to geometric altitude will happen soon, at least above the mean
altitude of the tropopause (32K feet or so). I personally believe the
pressure sensor requirement should be eliminated for badge/diploma level
approval.
