No they shouldn't. Not just because they skated cleanly a program they've had for at least 2 seasons or more. Granted, Lu/Mitrofanov deserve credit and good marks for skating well on everything. But they do not deserve as high PCS that they received, IMHO. They are pleasant to watch and I've always enjoyed watching L/M, but they still leave something to be desired in terms of expression and connection. They are young and still developing in that area.
L/M may deserve to be slightly ahead of C-G/L, but no way ahead of Calalang/Johnson. I would have L/M around 67, not 69. I also think U.S. fed needs to realize that K/F are a new pair despite how well they have come together. That means K/F have to make a good impression on Worlds judges who will not be interested in giving them anything. So treat all of your talented pairs fairly, and try not to exalt one team way above the others.
The slight double foot by Alexa on her throw landing would likely have been caught by international judges and marked down. Maybe K/F could score around 70 or so for this program starting out as a new pair internationally. I'm not sure how international judges, would rate K/F, but it wouldn't be 77 first time out. I think 74 to 75 would have been a reasonable score for K/F at this event, and perhaps 70+ for C/J; 67 for L/M, and a close 66 for Ash/Tim. The protocols show that the judges dropped C-G/L down another point to 65 behind L/M. Somebody really has it in for C-G/L -- a way to beat them down when their confidence is shaky.
It should be clear that C/J possess a world-class high level of quality skating! Just because both Jessica & Brian have trouble consistently landing their sbs jumps does not make them weak on their world-class elements. Lu/Mitrofanov wish they had the caliber of 3-twist, lifts, skating skills and magical connection that Jessica & Brian have in spades. Even though NBC highlighted and touted Knierim/Frazier's triple twist, Jessica & Brian have the best 3-twist out of all U.S. pairs teams. It is so high, light and effortless. They make it look so easy, and it's not. K/F also have a superb triple twist with great height, but maybe a tad less high than C/J's. The judges noticed accurately in this instance. If you check the protocols, you will see that K/F got one 3, one 5 and the rest 4s for their triple twist. Jessica & Brian got straight 5s across the board on their triple twist.
The problem for both Jessica & Brian is that they received straight -5s for the error on the sbs 3-salchows. And it's NOT just Jessica who has the problem, though it always seems to be highlighted when she falls or has problems on the jumps. Toward the end of last season and earlier in 2020, Jessica began landing her jumps better, and then Brian became shaky. Then they both got it together for 2020 U.S. Nationals fp, and made a huge impression with their clean skate. Next, at 4CCs, they both were a little sketchy on the jumps, but great on everything else, placing third in the fp over Kirsten/Michael of Canada (and 4th overall). C/J had momentum and then they got the Worlds nod when Chris K retired after 4CCs.
Unfortunately, both C/J and Cain/LeDuc had the misfortune of not being able to attend Worlds because of the cancellation due to the pandemic. That opportunity was crucial for both teams to make a good impression internationally. For C-G/L, it was a chance to redeem their season, and for C/J to continue through with the momentum they had coming out of Nationals and 4CCs.
