Olympics 2012 track cycling

So:
All the attention on what was happening on the marked lines is very silly.
The no drawing away early rule is quite silly, but at least it's arguable it was fairly applied to the GB and Chinese women.
Except that on the same interpretation some of the men's teams should have been DQ'd too...
So actually it looks like they were looking at who lead across one or the other of the marked lines. Or making it up as they went along.
?

I don't think it's a silly rule, it's the same as having a changeover zone in the 4x100 relay, there needs to be some rule there to make sure each rider does their full turn.

With some of the other rides that didn't get DQ'd I think it was simply poor judging those cases, they probably should have been DQ'd but got away with it because the line judge who was watching for it wasn't on the ball. Someone elsewhere has argued for line cameras for these sort of decisions to take out human error and I make him right.
