Hmmmmmmmm some "news" about the quad situation. Some guy replied to a comment on Youtube and I got a notification because I'd commented on it myself months ago. It's a Youtube comment so no way of knowing if he's telling the truth but here it is anyway:
"Really? I'm friends with his choreographer and believe me, they are not thinking about Yagudin at all. Jason is one of the most talented skaters in a long time and he has been landing quad toe's for almost a year, they just weren't ready to put it in the program.
Anyone who's actually a figure skater will tell you how incredibly amazing Jason is (not taking anything away from Yagudin who was of course fabulous as well). He's completely on track and in fact ahead of schedule as his coach and choreographer were not planning on him making the Olympic team. The next 4 years will be amazing to watch!!!!!"
So if he really is Kori's or Rohene's friend then we know that Jason has been landing his quads for quite some time! It took him, if I remember correctly, about a week from 1st landing his 3Axel to putting it in a program in competition (Jr GPF 2012/2013). His comment in that IFS article about how when the quad is there it will be in the program the next day - that's pretty much exactly what happened with the axel.
I'm itching to ask him/Kori whether they've considered 4Flip! I still have my press creds from early 2000s when I used to write awful articles for Cosmopolitan Finland (don't judge me, they paid well and I was a poor student

). Wonder if I posed as a serious journalist they'd grant me a skype interview? Don't know how I'd explain why Cosmo wants such an in-depth article about figure skating between bedroom tips and lipgloss reviews though
