I might have heard it differently, thought this intervention came way before the match but could be wrong.That is what the rumors said that Tom was responsible for the mode changes that increased their speed.
Tom has a amazing drive to win. In the first part he talks about how he and his coach knew there was some variation in the setups of one design boats he sailed. They got a hold of every combination of variation and sailed them until he optimized the modes on how to sail each variation. He then would measure the boat that was assigned to him for the regatta and knew exactly how to sail it as fast as possible.
My other takeaway was how much he would rather be on an Australian team, but this will do for now!
Also dropped in that during AC36 he had serious FOMO, and followed it all, read all the FORUMS too.
So if you're reading this, g'day Tom
