It doesn't matter what you or I or anyone else likes or doesn't like. A fall is a major error and a mistake. You can't just ignore it. PCS is supposed to evaluate the program as a whole...one cohesive unit. A program with a fall is not cohesive, or rather is certainly less cohesive than it would be without a fall. Dropping one component out of the five from 9.75 to 6.75 for men in the FS equals a PCS drop of 6 points. When top men are getting on average 200 points, and scoring 300, 6 points is pennies and does not adequately reflect the scale of the error.
There are falls and there are falls. At Worlds 2017 Jason fell on his opening 4T, was up in a flash, performed the rest of the program brilliantly, and got a huge standing ovation. That is a very different situation than, say, Daniel Samohin’s fall at SA this past year, or Jeremy Abbott’s fall in the SP at the 2014 Olympics, both of which really disrupted the programs and totally shook the spectators. I don’t see how you can equate the two.
