Why do you need calculus though?
Underrotated jumps and jumps with edge calls being 'derivatives' of fully rotated jumps

But seriously though, it's just spreadsheet math.

Why do you need calculus though?

I am curious the most about GOE work after changes and new scale introduced, especially in Ice Dance. In general, I am preparing a small card to cover scoring box while watching competition - I do not want to spoil my confusion at the end...
I find new GOE scale much better explained in ice dance. Some implications of new scale are:
1) You get mandatory -5 with fall by both with serious errors and -4 with fall by both or many errors (like stambles and loss control in steps, turns, holds, glide, errors in spacing, unision, in beat, style and character of the rythm)
2) There are features which worth double. Quality (correct, clean, sure edge, step, turn), deep edges and smooth/eforthless execution in dance patterns as innovative/creative element and smooth/efortless execution in required elements. For +5 GOE you need to have all double features in pattern and at least 1 of 2 double features in element. So non creative/innovative element could get +5 if it hit all the other positive features.
3) You cant get +4 with one negative feature, all must be positives (7-8 of them). To get max +5 in dance patterns most chalenging could be in perfect unision and max utilize space/ice rink during pattern. To get +5 in required elements most chalenging will be to have entry and exit on elements and maintained or accelerated speed during execution.
Example 1: Nathan is clearly the beneficiary of these quad rules.
thanks a lot for a break-down
Still, it's only on paper now and theoretical explanation and usage in practice ftor me are two different things...Judges probably will find a way to make a candy galore out of this.
Do they use Exel at ISU?Underrotated jumps and jumps with edge calls being 'derivatives' of fully rotated jumps

At my previous place of work there was a granny who used sheet of paper and calculator first, after that she slowly typed the numbers into Excel tables.Do they use Exel at ISU?

So the answer is yes, they do use Excel at ISU![]()

Want to bet that granny wouldn't have made the 4A < mistake even while doing it that way? Sigh![]()

I was also a fan of having to hit the requirement of a jump being high and pretty to look at before getting GOE points on other things like tanos or hitting the music,
but looking at it now with +5/-5, it's just confusing and if I were a judge, I would have so many things running through my head in that second the jump goes that I would just kind of wing it by feeling.![]()
And of course when there are both positive and negative qualities judges need to decide how to add and subtract to come up with a final number. Or in some cases they need to decide, e.g., "That [landing position/spin position/edge quality/etc.] was not good, so I can't award the associated positive bullet point for good quality. But was it bad enough that I need to reduce for it and thus cancel out any good qualities I can reward for?"
I've been thinking about this for a while, but wouldn't it be better if judges just tick off the bullet points applicable to that element, instead of forcing them to mentally calculate? I think some posters mentioned this will take more time from the judges, but would it really? Especially since there are only 6 bullets now, and about 8 possible errors eligible for deductions, judges can tick off appropriate ones, then the computer programme can produce a total GOE score. Ticking boxes doesn't take long, and it would reduce maths processing time for the judges. If anything, it forces judges to evaluate elements by the guildelines, instead of going "Oh man, Hanyu just landed 4Lz, time to +3" or "6th quad from Chen, +3 for effort".
That is, of course, assuming the ISU even wants transparent and fair judging![]()
The Nathan Chen Anti-Yuzu RulesPretty much. We should just call these the Nathan Chen rules.
It's kind of pathetic this is what they do to get him to win but .... especially as the impact to the entire sport is so horrid. Like, give the guy the gold medal in advance in 2022 and get USA off our freaking backs that way, but for heaven's sake, fix these idiocies and don't ruin the whole thing.
I still think the Russian ladies will be fine though. It'll be more tight but they should be able to work this.
