I’ll have to look up his IJS scores, but generally Jason is extremely athletic, has fantastic presentation scores and has great technical skills. His form for his jumps is better than Nathan’s, or Vincent’s. So - you do a fantastic quad but get a low Grade of Execution because it’s underrotated or poor form (essentially how well you DO the jump) vs Jason doing a triple axel-triple loop (the highest base value of the triple triples) with a higher GOE, one outscores the other.
Also… it’s a judged sport and Jason has been put in SO MANY promotional videos. But I think there’s a possibility they send a bunch of the quad boys to Beijing.
