The only thing of concern that Jason should need to prove is if he can score higher than Vincent--that is the only relevant thing. I said very clearly Vincent needed to work on his skating, and I simply stated that Jason scored lower than Vincent, he was not "smashed", you made that up. Vincent landed two quads in one competition, jason has never landed one in around two dozen, though clearly he has better skating/artistry.
Again the point is Jason needed to prove that him placing below Vincent was due to his injury and he failed to do that because he scored lower than Vincent and didn't improve on his own program. As a matter of fact, most of the mistakes he made at 4CC were the exact same ones he made at Nationals (fall on 3A and ur 3LZ in short, botched 1Lo3S combo in free plus he popped an axel at 4CC) and he didn't add back a quad/change the layout either.
