Unlike some people, I don't think the USFS are being babies about this. They are just asking for it to be re-timed. If she did go over, then ok...on to the LPs...if she wasn't then the .2 points should be given back and the oridinals re-done to see where MK stood.
And it is a big deal considering MK could be anywhere from 2nd to 4th...if she's 2nd then she's striking distance from the gold...if she's 4th, she has to fight to go on the podium. That's why the USFS just wants to make sure the timing deduction is justified.
IMO, I think it's good that a federation is looking out for the interest of one of their skaters.
