Rubens thinks that maybe Honda's problems stem form the wind tunnel, seeing as the gains in the tunnel are not finding their way into the circuit.

why not, its happened before with incorrectly calibrated wind tunnels, and it would go part of the way to explain why the team were so hopeful only to be dashed by the fact they'd made a lemon - could they have cocked it up in the tunnel? is the wind tunnel meaning they are going wrong with the improvements they are making?

or have they, as stated elsewhere, dug themselves a whole by losing Willis, Davidson, maybe even Richards and Villeneuve and hiring Nakamura and Fry etc and now don't have a clear idea how to build a fast car and are starting from scratch again?
