That's a bit of a gamble. If McLaren hadn't dropped the ball so
frequently, RBR would have left themselves too much too do. They'll
have been giving it a maximum effort since the start of the season.
The thing with RBR is that nearly everything they bring to the track
for the first time seems to work. There seems to be a very good
correlation between what they find in the wind tunnel or via CFD and
what actually happens on the track. Plus they've kept on working on
and testing new parts and have come up with something that has made a
big difference at a critical stage in the season.
