Thanks. But no matter what, the real time-stealer is the endless kiss 'n cry wait times
What they're waiting for is mostly the tech panel reviews.
Or for commercials to be over in some live-broadcast events.
Do you think it might work if they experimented with judges in-putting scores for each skater in a segment as they usually do. And when the performances are over allow a set time of two minutes or less tops in the kiss 'n cry for photos and quick program slo-mo, while tech panel confers briefly. But then don't announce the score at that point, simply move to next skaters in that segment. Once that segment has ended and the next group is warming up, have the tech panel address any concerns they had with any of the skaters' performances in the prior group before finalizing and posting all the scores for that group. This might be a way of just experimenting to see if they could save some time by limiting kiss 'n cry waiting.
If you aren't going announce the scores then, audiences would be even less interested. They don't get to see the skaters reacting to their scores, which is the main human interest reason for having a K&C to begin with.
If you allow time for quick reviews immediately after the performance and more/longer reviews during the next warmup, if there are several messy performances with many gray areas and confusing calls, six minutes might not be enough time to clear up all the questions remaining for the previous six skaters. In large events, with resurfaces after every 2 warmup groups, there would be time to catch up on any reviews that had been missed earlier. Except for the last group, which in the freeskate is the one everyone is most interested in.
And it's not just the tech panels -- judges need an opportunity to adjust their scores based on what the tech panel calls. E.g., if they gave significantly positive GOE and the tech panel calls a << or e, the judges will now have to make sure they have subtracted 3 or 4 grades from all the positives and will probably end up negative.
Similarly if the tech panel changes a call from, e.g., CCoSp to CoSp because the error at the change of foot was of a nature that caused the second foot not to count, or the like.
However, if you give judges access to change their scores for earlier skaters after they have seen the later skaters, that gives them more opportunity to adjust their scoring based on what happened later with other skaters, i.e., consciously dishonest or unconsciously not their honest in-the-moment assessment.
That problem could be mitigated by not giving judges access to change any of their scores except the specific elements whose codes as shown to the judges have changed after the reviews (edge and rotation calls being considered part of the codes, but not levels because those don't get shown to judges).
In any case, judges should not have the opportunity to change PCS after the reviews.
I think the biggest drawback for audiences would be having to wait more than 6 minutes after the last skater finishes before being informed what the final placements for the whole final group were.
Should it be tried out someplace like Nebelhorn, where they usually try experiments? Or does it need to be tried at an event with a larger live audience and multiple live broadcast networks?
