Yeah, that's exactly why I created a new method for brushed outdoor quads. I forget exactly what post number it was born on but here is the short version:
Step 1: set yaw P to about 90, and all I values to somewhere between 75 and 90.
Step 2: pick a really windy day and go fly a leisurely straight line under fpv while the wind is knocking your micro around. You will see big bumps. Raise P on both pitch and roll till the big bumps turn into very tight very high frequency oscillations. If its a really day you may still hear them, and that's OK. You just want to see smooth video at the end of the whole process.
Step 3: go fly the same straight lines and raise D on pitch and roll till the tight oscillations when it's pushed on by the wind or turbulent air smooth out visually.
All done. Quick and simple - no crazy flying needed
Ocassionally I will do a straight down SLOW decent while flat into my propwash and apply the same method - but it will never get totally perfect there. As good as you can get it on that is kind of fine tuning.
