Sorry, but most of the "activity" is actually on the back of the wing: I wondered about this myself: The issue here is that the CL collapsing down and moving forward of CG (as is absolutely necessary for the theory to work without perceptible pilot effort)
does introduce the issue of suction...
I doubt the turn-induced imbalance accross the propeller face would introduce greater pressure on the wing, so it has to be greater suction...
There definitely is suction ahead of the propeller blades though: That is how the prop works... And slower incoming air on the inside-turn side of the prop does create a greater suction ahead of the inside-turn area of the disc as the blades go through it...
An actual aeronautic engineer agreed with me on this, just not on the amount and significance...
It would be interesting to know if this imbalance was looked at and quantified: Given the low-tech nature of the prop era, I sort of doubt it...
As for Shaw, his evaluation of how the P-47 was used tactically in WWII is laughable: Even if you added up all his examples of "significant" dive and zoom "energy" tactics, you still barely end up with one quater the amount of 109-beating multiple circles combat quotes I have come up in
one post... Including down on the deck at 140 mph...
Remember, for Me-109Gs out-turning P-47Ds in sustained turns, I only ask for one
tenth of the amount to be impressed...
I came up with two from the same pilot, remember? Let's not count those in right away...

P.S. About Hurricanes being magically out-turned by Me-109s, have you asked RCAF Hurricane pilot John Weir?
