Not sure what's going on with the salchow but maybe it was with a difficult entry or she's just not used to the program yet. The 2Lo<< was just a normal pop that looked like 1Lo. It was an obvious pop while the 2S looked so natural that I wasn’t sure if she popped it or not although it did look a rotation short. And I see that she received positive GOE for it too.
I was looking up her past protocols to see what she usually pops and found that she’s already received a ! on the Lutz at the same competition 2 years ago. She didn’t get a ! on the Flip there either.

She has received < or << on the 2nd 3T 3 times in 2014-2015 and 4 times 2015-2016.
I saw her live at PIW Tokyo and she skated clean for
Byakuyakou although she did pop something during the group performance with Nobu, Sota and Yuka. The lady I sat next to said that she was clean at the previous show as well. I think it’s just a matter of getting used to the programs.
