What sort of aircraft are we talking about here?
The TAS difference at 2900' density is less than 5 knots - i.e. you would expect to see nil wind gps speeds (or directional averages) about 5kt higher than observed.
As for gps giving too high a speed would not the horizontal component of velocity be less given any descent (or climb) since you can safely assume WGS84 to be 'flat' over such a small distance?

Anyway - has anybody had any really good, positive training experiences pertaining to stalling and slow flight? That should bring us a little closer to the original thread, too...
