EMS - I actually said he had to use more power earlier in the approach than usual - if he was downwind he would have lost ETL sooner. His unusual power requirement (the call of limits) appears to be the first time he recognised there was something wrong and the fact that he needed 15 degrees nose up to arrest his unexpectedly high groundspeed only serves to confirm the downwind scenario. Flare effect needs a change in inflow angle to produce the increase in rotor thrust but when the wind is behind you and your airspeed is low (or negative) this doesn't happen so the flare is far less effective.
