Thanks for those splits. BTW: How fast were Lemaitre’s relay splits? He looked quite good against Thompson in the semis, and Thompson split 8.94 in the final. Maybe the first caucasion sub 9s relay split? 
The early and slow changeover between Bolt and Powell makes Bolt’s split look quite unimpressive. I’m sure it would have been below 9s if they had exchanged a little later and at a faster speed.
