There was a significant following wind during the race, so I think this record will be very hard to beat. I agree with Economist, 9.7 will be a tough ask- and breaking 9.6 impossible imo.
Been said before but Powell has no mental fortidude. At the Olympics and in Osaka the other week you could tell from his eyes and body language that he was petrified before the race had even begun. He then went on to say he gave up the race when he knew he couldn't win. Talented athlete, but very poor attitude.
