I've got an idea! I think it would make judging more fair/ correct, and would also cover national bias. The idea is inspired by the fact that the tech panel votes to reach a conclusion and it was mentioned that in gymnastics each judge judges just a portion.
Tech panel would do the same exact thing. To avoid national bias there should be no 2 persons on the panel from the same country.
The panel of 9 judges would be split in 3 panels of 3 judges each, and they will vote and reach a single mark (conclusion, see lower) so each single national biased mark/opinion will be outvoted in the panel.
Each panel can judge everything as now, or we can have each panel specialized, one for GOE for jumps, one for GOE for spins and step sequences, one for components.
The panel in charge with jumps double check the calls for edge and underrotations (tech panel would be placed on the opposite side of the rink than the judges, or at least this panel). The judges could not improve the call, just diminish if the tech panel called a jump clean but the judges see it under, it will be under, but not the other way around.
Ideally, each panel would go through all the bullet points and vote on those, and the computer will give the GOE. I think they should have enough time to do that in 2 minutes.
