The Skate Canada practice shows he can do the FS with all the jumps, including the 4T (well save that wretched 3Lo

). The NHK Trophy issues was truly one of nerves, IMO.
I think all the constant layout changes is probably another source of inconsistency. He likely practices at about 3 different SP and FS layouts, based on what we've seen in summer competitions and during the GP. But in the long-term this might be a good move cause basically he can kind of improvise, as we saw in NHK Trophy FS -- I mean he even threw a combo he's never done in competition before -- and prevent any Zayaking and maximize points I bet if he pops the 4T or 4S into a 3T or a 3S (or worse case scenario, both) he actually practices a layout like this:
3T
3A
3S
--
3A-1L-3F
3Z-2T
3Lo
3Z-2T
2A
Which has the same number triples as his no-quad layout
3F
3A
2A
--
3A-3T
3Z-1L-3S
3Lo
3Z-2T
2A
Or what if he pops both jumps into doubles? That's like super worst case scenario, but it could look like this:
2T
3A
2S
--
3A-3T
3Z-1L-3S
3Lo
3Z-1L-3F
2A
Because he's been working on all these 1L-3S and 1L-3F combs, he basically has way more flexibility if he has problems with quads.
And to his credit, his improvs at NHK actually helped him to be a little bit closer to qualifying...even if it didn't work out.
This is much different than 2013-2014, when basically stuck to his layouts from the second-half of last season (with a few changes due to choreography). And last season, he basically did one quad in both programs all season until he got injured and they had to build his way up again.
This is very much reminiscent of the 2012-2013 season when he was incorporating the 3A. He was off the podium at JGPF, which was a major issue given that one of his main competitors at the time (Han Yan) wasn't even in JGPF and he had beaten pretty much the rest of the field at some point (including Josh, though Josh had been victorious in recent head-to-heads). Nobody expected Maxim Kovtun to breakout when he did and all the 3A issues did him and Ryuju Hino beat him. BUt then he went to Junior Worlds and won the FS with a record score that stuck around for nearly two seasons. Also he just doesn't peak in October/November, even when he's healthy.
The programs are harder, I agree. The amount of jumping in the Hamilton choreography is tiring--I mean, there's all these photos of him in mid air, and they're not of him doing actual jumps -- it's just choreography! The FS looks "easy" but there is a ton of multi-directional skating and not a lot of crossovers. He basically uses edges to get to one side of the rink to the other. There's also a variety of different transitions -- a lot to remember. While I think Adam Rippon has strong performance ability and beautiful positions (and good for him for being consistent on the jumps)-- there is not a whole lot going on in between the jumps. He does have transitions --but they're actually pretty similar. I think judges know the difference, hence the 89/90+ PCS. In spite of everything, Jason's still the top scorer in PCS and that was considering some major score increases for Adam at Skate America.
It's a bit of a long-game, which is kind of hard to do when there's a sense of urgency with the Olympic year -- hence all the repeating programs! But yes maybe not being at GPF -- if he doesn't end up there -- might be a hidden blessing to master everything.
(Side note: I also think he could battle the Shibs in a twizzle-off, LOL.)
