The Plushenko-Lysacek showdown is one of the few times I remember U.S. people outmaneuvering Russians. Whatever information circulated about "transitions" -- which Mishin held in scorn, and judging by Tukt's programs, still does -- was countered by complaints that Lysacek under rotated his axel. At Skate America in Lake Placid, Mishin sat behind the tech panel, stood up after Lysacek skated and ostentatiously leaned over, as if to check if they were going to call a downgrade. (They didn't.) He also bitched at length about Plushenko skating early in the short program, claiming that judges would hold down the marks.
Inman's email hurt Weir more than Plushenko, IIRC. Transitions weren't as big a deal in 2010 and they are just one of five PCS. Overconfidence cost Plushenko gold, all he and Mishin had to do was design the layout of his free a bit better. But whatever Plushenko lost in 2010, he was compensated for in 2014, when IMO some of his scores in the team event (spins, in particular) were too high.
