I don't think it's the best idea for everyone to know how to "trick FOQA" for the most part.
Edit: just reread your post. Not sure if the 45 knot high speed is real or not. I don't know how the airplane knows you're on a high speed exit or not. I'd imagine once your below a certain speed, FOQA starts recording taxi speeds over 30 knots, so maybe that's where the 45 knot comes in: GS below 45 knots after landing activate 30 knot limitation.
When I was at Republic, I was told by the FOQA people that it doesn't register taxi speed until flaps are "UP"...hence how it can tell you're on a high speed. Go home legs would normally see us taxiing in with flaps accidentally set to 1. While at CP, I never knew if that was how they collected the data or not. I always took high speeds, especially in LA, at whatever speed we made the high speed and wouldn't call for flaps up until off all the runways.
