The quick turnaround for Yuzu's attempt at a 4LO and the announcement from the ISU makes me wonder if the ISU, being made up of humans, like us, had a long argument about Alexei's 4LO attempt but then, before they could come to a conclusion, Yuzu's 4LO was done at Autumn Classic, it was clean, so they just said, "Hey, let's go with this one."
Or, they took one look at Alexei's 4LO, decided it wasn't going to go through, but didn't make any announcement because they didn't know what to say. :think:
