I see the problem, but would it still be worth superimposing the official AoA trace on your graph, for comparison purposes: uncorrected and perhaps also corrected by the Prandtl-Glauert "rule"?
Thanks for both suggestions. I've added a note to the graph and the post.
Adding the 'official' AoA doesn't seem practical: The AoA trace is on figure B2, which has a different timescale from figure B4 that I used, and 10 degrees AoA is only 3 pixels.
