Yes you're right, thanks for reminding me. I should have already known this because the technical sheets were fully disclosed for the Olympics.All skaters are required to submit a Planned Program Content (PPC) at the time of entering the event (or are meant to submit it). The elements get manually entered into the ISUCalc program before the event (I did them all for our National Championships a few weeks ago and it took hours - arghhhhh!!!).
The judging sheets are then printed for all the judges and technical panel and they list all the elements that the skater has submitted on their PPC.
Doesn't mean that is what the skater actually does as the tech panel and judges evaluate the element as done, but you get a good idea of what they plan to do.
Also the +COMBO part doesn't need to be data entered anymore as you can tell if there are two jumps for that element that it is a combination, but the +SEQ does get used.
I thought +COMBO was still used in instances where a combination should have been completed in that instance (either SP or Zayak rule), but was omitted.
