I am not affraid to admit when I'm wrong, and feedback is one of the things I appreciate here. However, it would have all been a lot easier if it was constructive, rather than bitching with an undertone of "my driver lost out, you're wrong".
So I've updated the article, correcting my calculation mistake with Massa after France and his pit in Singapore, which when you get down to it, would also constitute bad luck. Now that paints a whole different picture!
