I think Mark was on the gun strategy for Canada. I think they all assumed they would have got more out of the first set of hards...getting the softs on last fro a run on a gripped up track was the place to be, especially if you had to make up places for a grid penalty. But traffic was terrible. If you were watching th elive timign you would have seen everyones times bouncing all over the place. Webber was affected more because at the time he was flying solo. When a guy racing sees a single car come up and gets the blue flag he does at a very opportune place so that his race or position is not compromised. When you have Alonso, Hamilton, Button and Vettel all marching up on you they tend to move over easier as teh train comes through
Still, not a bad weekend for Webz, and I have to say great weekend for Louise Homoton
