Don't call it tail rotor VRS because it most certainly isn't - we used to show this on the Wessex to highlight a wind from the 10 o'clock would cause yaw deviations and could lead to overtorque, especially at high AUM. On Bells like the 206 it just leads to LTE.

To get VRS on a rotor it has to be moving into its own downwash at a minimum of half the speed of that downwash - normal yaw manoeuvres and crosswinds don't even come close to that speed.
