Marcel Hacker's Stroke Cycle

The pictures below (scroll right A LOT!) are of Marcel Hacker, runner up in the World Championships 2003. (He was the hot favourite to win).
The source is (with permission) from the FISA DVD of the Milan World Championships 2003.
There are 52 frames, each representing 0.033 seconds.
The stroke rate is 35, with the recovery to drive time of 27:25 (it's difficult to be exact about where one starts and the other finishes.)
