There are definitely changes to the system needed.

I tend to agree with Nigel re. round robins leading to a draw rather than prefixed matches which could be detrimental.

The Algerian runner should have run his best for half a lap, then limped away with a "sore" ankle! Simples.

Nonetheless, this was a stupid reaction which should not have occurred. I think it very likely that he was the fifth disqualification of the badminton scandal. Had that not happened, he would have been O.K.
