Sure, it's going to vary, even within a state I have had the scores for virtually the same routine vary up to a point. The areas of deduction on this routine aren't huge though. She should get a small deduction for her body position when jumping to low bar - .05-.1. Then .2 on cast, .05 arms, .1 rhythm, high bar cast I suppose they could take .3 but I think most judges would do .2, .1 rhythm and shape on back hip, .1 on both swings for excessive piking. Then some foot form in places, .05s. Max you have a little over a point in deductions so 8.9 on the low end and up to 9.1 on the high end.
Of course the judges can do whatever they want and in some cases judges do what they want. But using the text that is about where it should be. The USAG presentation on compulsory scoring which we had presented in our state was very informative (USAG put it together, not my state - they had experienced judges judge routines that had been videotaped across the US, with input from the compulsory committee, then they put it together in the presentation showing the range they were at). They did an excellent job. Where these judges really succeeded was in differentiating between the quality of the routine. Yes, in some states this might score a mid 8, while another routine without the same quality of swing would get a low 8. There is no meaningful differentiation between the quality of the movement. And some of those judges and compulsory committee members gave some routines, even with visible (but less significant technically) errors high 9s (9.7s). So they weren't afraid to do it. They just used the text, and that differentiated bad from good from great. On the other hand they showed a more or less competent level 5 floor routine. The child landed everything successfully, no squats, no falls. Somewhat loose but the tumbling wasn't bad. This routine would get an 8 something pretty much any meet in those country and I watch YouTube obsessively including CA, never seen a routine like this get a 6 or 7, but the committee gave it like a 7.1 or something. Again differentiating loose from tight with some errors to tight with great amplitude.
By their scoring, which they did as a range, they ranged level 4 bar routines like this from 8.8-9.0. You don't have to be amazing to get a 9, you just have to have a point of deductions, which if most of your major elements don't have severe issues isn't that hard to do.
