Sorry if this is off topic.
I don't think the reason Pang/Tong has not been doing so well this season as the last season is because of her weakness.
It's mainly because of Tong's inconsistency in his jumps.
He has been struggling so much with his jumps since the beginning of this season, while Pang had looked much stronger in her jumps.
It seems like he never can land his jumps cleanly, and that costs them huge amount.
I wonder what happened to him. Is he seriously injured?
About her weakness at 4cc, I hear that she was suffering from injuries and boots problem. Someone who attended 4cc said that she looked feeling uncomfortable and irritated in her shoes, and even afraid to skate.
