Sarcasm aside, I don't think that IOC knows or cares that much. Rather, it's way simpler than that: the events with lower viewer figures are scheduled early in the games, even before the opener, to save the prime time for events that are popular with the public.
I think you are entirely correct about early scheduled events, etc, but I also feel that the Team SP events could be done in one day, followed by one day off before the Team finals which would occur the third day. (For that matter, maybe it'd be fine to have all the Team SPs one day and all the Team Finals the next day.) Then there would be a decent rest period for everyone, before the individual SPs which wouldn't begin for 5-6 days and which would NOT be scheduled just one per day. That 5-6 days would allow a better break for everyone. The break for Ice Dancers and Men of 'only one day' between Team LP and individual SP seems almost intentionally cruel.
For that matter, why on earth are the individual events ALL scheduled just one per day? If they were scheduled later and were two per day at a time, not beginning until after 5-6 days of rest following the Team events, 'skating LP programs again' wouldn't be much of an issue.
I believe there is a way to decently handle this, for Ilia and whomever else may wish to rest instead of skate the Team long program full out. Skip the interviews, celebrations, parties, etc, after the Team event finishes. Team medals need to be given out RIGHT after the Team event finishes. Then, everyone who skated, go get some rest, find a good masseuse/masseur to rub the muscle kinks out, have a leisurely shower or bath, eat a decent but healthy meal, then sleep, and next day, train 'as usual' which generally means two 45 minute practice sessions per day. Don't kill yourself doing lots of extra off-ice exercises.
Next, prepare for an SP you may not win. You can even change one difficult quad to a triple if necessary. Then, plan your LP to do what is necessary but not more than you can manage that day. Example--seven quad programs are NOT required if you can do better with only five. But go according to how you feel that day of the individual LP. If you feel you can go all-out, then why not do so?
Nobody needs to kill himself or herself trying to do some 'Olympic event moment' Team event; watering Team events down is fine. Not coming in first is also fine--so long as it's no worse than second, or maybe third. It's also okay to 'just say no' even if doing so causes your team to lose a better medal or placement than they would have received. I can almost guarantee that anyone skating in the LP as a 'replacement' skater isn't going to be going all-out in the Team event, either, even if not a real medal threat.
Just some thoughts here. I wish every skater a great skate, and let's face it--the Team event which should be mostly a just-for-fun 'bragging rights' add-on is turning into an Olympic monstrosity. I watched Day 1 on the German channel using my VPN and might get to watch Day 2 and Day 3 IF I can find the proper links. I have the one for Day 1, but I'm not German-literate so I've no idea how to find any other events there. If anyone can help with that I'd sure appreciate it.
