Hammerhead. I've looked at the photo........and the tyre marks. Well according to the tyre marks you are correct!!
(massive climb down from Splashdown!). All I can think is that the camera lens foreshortens the whole aspect of the photo, since at that point I would expect to be virtually scraping the fence with my shoulder. You don't obviously, (always think of Alex George going through Ginger Hall), but that was the feeling. This rider MUST be online according to those marks you refer to, but my first impression was that he could have been further in.
It would be interesting to see a top notcher at exactly the same spot, but I feel that I will have to concede this one.
