The RAF, it seems... "d. Still-air planning is to be used. When the wind speed is greater than about 10 kts, MDR techniques should be used."
Probably has a lot to do with the fact that on the F214 wind chart, the windspeeds are given in multiples of 5 i.e. 5, 10, 15 etc. The 5 knot wind will not have a direction provided i.e. it will be VRB 05.
Thus if the wind is forecast to be less than 10 Kt i.e. 5 Kt or Calm then it makes sense not to fuss about with trying to guess a direction.

Online planning is great but how many flight briefing rooms in the UK have internet access? - not many. I often find now that we end up going into the terminal to use a WIFI connection or some other public internet facility.
