Wow. Thanks for the feedback. This is really the only _best_ way to making
sure the feel of the flight modeling is right - getting the qualitative
reports from many people is even better.
P-Factor is definitely one of those effects we need to adjust based on the
qualitative judgment of people

It sounds like you certainly got your money's worth from the test flight.
