What is interesting in the vid is the effect of the wind gusting. I used JJJ65's ME and implemented the Wind feature which uses OldHat's wind mod built in. I was flying with wind between 7 and 9 knots and still had some extreme effects. Possibly a little more than should be there IMHO but still a desirable effect.
Yep, I agree that 7 - 9 knots is rather too much for this kind of wether. I always made manual adjustments to wind speeds and fill in values at least 2 - 3 knots lower than recommended (prefilled). In your case I would use 4 - 6 knots. Just my 2 cents. Anyway, I am glad you have tested it.
