This is academic, and not related to the overall discussion, but I have to defend Stolbova/Klimov's honor.

First of all I do remember press reports that T&M were asked at the last minute to do both events after S&K weren't invited, but said no because of a minor injury, so the nod went to Z&E. Plus I still have the spreadsheets I made going into the 2018 team event

I used season's best scores going into the Olympics. S&K's SB was only 1 point behind D&R's, so I had them 2nd to D&R in the Team LP (S&H had the highest score but my SP predictions didn't have China advancing to the final), or potentially in 1st ahead of D&R if we used personal best scores (from the time S&K landed the triple triple and won GPF). S&K arguably had a dark horse potential for an individual bronze if they skated their best (they probably wouldn't have beaten the skate D&R actually laid out in the individual event, but that was 5 points higher than D&R had gotten that season). S&K ended up 5th on the overall SB list for 2017-18, about 10 points ahead of Z&E, and beat Z&E at Nationals and Euros. Z&E also didn't medal on the GP that season, so I don't know where this idea comes from that S&K were not clearly the #2 team. In fact, Astakhova/Rogonov won two GP bronze medals and had a shot at the third spot, and some people, including me, thought Z&E were overscored at Nationals to get them on the team.
Again, I understand that S&K skating in the Team LP wouldn't have changed the result even if they'd taken first, just thread drift.
