Stats and maths tell us a lot, disclose trends etc.
The skaters probably ignore all this, and just compete for what they are worth, hoping for the judiciary to do its proper job.
I believe there must also be people who apply these kind of statistics to the individual judges, trying to determine possible outcomes in scoring over different compositions of the panels.
i.e. what is the probability of skater x winning with panel composed of callers y1,2,3 and judges z1 to z9?
Are there? That seems almost just a bit dodgy.
