I don't think it really matters the length of the course (80 NM), you
average speed is still going to be lower than your cruise race speed due to
take off and climb to race altitude at slower speeds. I would agree that
the longer the course, the less impact the lesser takeoff and climb speed
will have on the average. It would appear that with an average of 216 mph
and his fight with a head wind ( you never recover the time you lost going
into a headwind by going downwind on the next leg) there was a 4 MPH
different between his average (which includes the adverse effect of the wind
and take/off) and his race speed.
In any case Tracy's race speed of 220 mph with some power held in reserve
clearly speaks for itself.

Not to diminish the results, but I believe the actual lenght of the
course is between 80 and 90 miles, not 100 miles, thus compensating for
the take off roll and climb. I could be wrong. Anybody know if the
average speed is computed from actual length of course or from 100 miles?
