I think her jump problems stem from her working to get her jumps to not get downgraded... it's her first time at worlds and she was probably thinking too much
You're right, that's very possible. But it was her first senior National's, too, and she skated phenomenally! (I thought she deserved to win the LP there.)
Maybe something was up with the ice, too. The British commentators mentioned that due to the number of people in the building, maybe the ice was softer than usual, which can have an effect (like slowing skaters down and not giving them as much of a spring on jumps -- I did feel like a lot of skaters were skating slower than usual, and the jumps lower too, so maybe that had a real effect).
