I'm not a technical caller but I'm a video replay guy on technical panels and I'm very familiar. I saw an outside edge on Mirai's first flip for sure in real time, I didn't even check the protocols. I'd have to look again at the second one. I don't think they just pulled it out of nowhere......She does have erratic edges on her flip, and I know for fact she's been called with "e" on flips in the past, this isn't new.
ETA: looked at the replay of all three jumps on Youtube, Lutz and both flips all very clearly went off a slight outside edge. The first flip is more outside than the second but it's there in both as the last edge before she takes off.
