1.00, failure to leave table before horizontal
I'd take .5 for insufficient height, maybe .2 for insufficient distance
.2 shoulder alignment, .3 bent arms
.5 too long in support
I didn't really look at landing deductions or foot form, and most judges might be more strict than me on the bent arms, particularly on the second vault (they can apply up to .5). I'm not a judge, but that's how I'd more or less apply the deductions. I'm probably somewhat generous, I'd go 7.1-7.3. Additional deductions could (probably would, by many judges) be applied for dynamics (lack of speed/power - up to .3), excessive arch in both phases (up to .3) and foot form in each phase (up to .1).
But I tend to think compulsory vault judging is a little nutty anyway and sort of double deducts. I don't care WHAT score my kids get in an absolute sense, but sometimes I get two kids getting the same score where I'm just like, these were not the same technical quality of gymnastics at all.
