Out of simple curiosity... What would you do if, say, a person gave a "10" level performance in group 4 according to the scale you have in mind, and then in group 6, someone gives an even better performance, which is now the "10" in your objective scale?You're supposed to set as accurate of a mark as possible within the objective scale and then reference that as needed. Nobody is getting judged relative to skaters to come, rather they should all be getting judged within the framework of an overall objective scale, but WHILE being mindful of scores that were already given, so as to properly rate each performance in relation to each other. Perhaps there is added difficulty to keeping many performances in mind while assessing each mark, but a great judge should be sufficiently capable of handling this task, and referencing the numbers would only serve to improve judging consistency and mindfulness.
For me, it is simple. I don't judge in real time, and can adjust my scores. This is an entirely genuine question.
