As I see it, Patrick has got that skidded technique in 2011/12 season.
You can see the difference when you compare that gorgeous 3A, for instance, in 2009 and the solid, not gorgeous but decent enough, 3A in last season. And I said in a previous post I was not worried about his jumps because I saw the practice at JO and his 3A technique was there. I'm sure he has not lost his jumps.
But what I'm worrying about is, after hearing the comment from Kurt and reread the above comment from Christy, that "bad" habits would creep in a stealthy way because the muscle memory is so strong.
