So far so good. I've learned how to break out still pictures from the video. Using my timeline (I took a stop watch with me on the flight) I took stills from each of the speed ranges I studied. To the extent possible I tried to be random in the selection so I didn't cherry pick a shot to match my conclusions. If anyone on the forum is an experienced Movie Maker user and you have any tips, please contact me off forum, otherwise, please don't laugh at my bumbling.

Interesting. It looks like you have smoother airflow at lower speed (i.e.
higher AOA) than higher speed. The flow seems to be disturbed form
surfaces farther forward, so I'd say the flow over the windshield is
smoother at higher AOA (which make sense from what I know of the Kolb
windshield shape).

Rick,
Interesting indeed. At the slower speeds, the only meaningful disturbance seems to be near the bulkhead/break just aft of the seats. Other than that, the tufts don't looks so bad and by the time the airflow gets to the prop area it looks pretty decent.
At the higher speeds, were you descending or flying straight and level?

All done in level flight.
