Fuel Flow

I think it caused by Fenestron. Fenestron takes less power in cruise flight.

Power absorbed by tailrotor. Classical tailrotor vs. Fenestron

Hover (IAS 0) 15% - 30%
Climb (IAS 75) 12% - 15 %
Cruise (IAS 135) ~10% - 2%!!

as you can see in hover parameters the Fenestron is not the best choice to hoist (Hover) operations. This not the answer, only comment...
