In Jenson's interview with the BBC after the race yesterday he mentioned that the car is getting tired after four fly-away races:

and the example he gave (at 1:25 in the video) was that the FFA (or FFAM) wasn't working. I assume he's talking about the Front Flap Adjustment (Mechanism). The lack of it obviously didn't prevent him winning the race however.
I remember seeing some quotes from a couple of other drivers earlier in the season also saying they weren't using it (Lewis and Fernando in Australia I think, but can't remember the source I'm afraid).
Looking at it from the other direction, I can't recall seeing or hearing anyone talking about having gained an advantage from using it.
So are these new adjustable front wings a waste of money?
