Cutted the fin one time personally at the controls, have seen a second time live and in colour and have heard about a few dozen times about it by ECD.
Thats the reason why the BK have still such an soft area on the right fin.
It's not a question of the RFM, simple a question of wind direction, speed and turbulence and be sure ECD knows everything about. In the RFM you will not find a single hint about it.
In my personally file the wind came with just 20kt gusts right about a 15m away airfield hangar in my 8 o'clock position causing intensive blade flapping during starting up the first engine.
