Pat Fry:
We brought some reasonably significant updates to the last few races and there’s more to come for the next ones.
It's odd that Alonso says things like there haven't been any updates for 6 races and Fry says this. I think it's clear to see there have been updates, but they may not have added much in the way of lap time.
Still, you would hope these rear wing variations will not go the way of the front wings earlier in the season, and that the chance to have run variations on this same theme for three straight grand prix will have given them to chance to figure it out. If so, I think they could see a decent step.
