As for Marin, I think her PCS should've been a little lower, but the TES seemed right. Also, it seems that she collapsed when she got off the ice, but I saw a glimpse of her walking while Mirai was heading to the Kiss and Cry so I hope she's okay now.
She collasped! Oh no! The have to do something about this altitude! Suggest the skaters come a week early so their bodies can acclimate. I'm proud of her putting out the performance she did when she was suffering from altitude sickness. It's no joke! The adrenaline pushed her until the end.
