The notation in dance on ice evolves regularly, which, as modestly says Guillaume, relativizes the concept of world record.
But in my opinion, if the maximum theoretical score evolves, it still corresponds to the notion of "perfection". It may well be that a total score of 190 today is not closer to perfection than a score of 187 2 or 3 years ago ...
Would it be wrong to reason in this terms of percentage, in relation to a perfect theoretical notation?
Currently, for a "perfect" score of 210 (exactly ? 85.4 SD and 124.6 FD ?) G & G would have a rating of 98.67% !
Is this reasoning realistic in your opinion, or are there influential factors that I do not take into account?
If someone is able to share here the evolution over the years of the theoretical maximum scores, I could thus "poke" a little in the results of the ISU to see what it could give ...
As a reminder, and this is impressive, here is the progression of the G&G average score for each senior season (CS and GP ISU, Euro, World, OG):
2013-2014: 135.15
2014-2015: 167.27
2015-2016: 188.59
2016-2017: 191.74
2017-2018: 201.21
