Exactly, If Amber does a 3A (8.0 points) and someone else does a 2A (3.3 points), everything else being equal. well, there's the base value math.
Is everything else equal? There are many factors, of course. But for instance if we take PCSs, judging panels seem to be pretty consistent across competitions. (I didn't research this, just going by observations and impressions.)
Amber typically gets 8.25-8.50 on composition, presentation, and skating skills, which I think is about right. Liu gets 8.75-9.00. No complaint there. Sakamoto, 9.25-9.50. All get a little less if there are technical mistakes, a little more if they are more-or-less clean.
Amber has to win on tech, which for her means two triple Axels. With one satisfactory triple Axel (base value 8,0, plus GOE} and one failed attempt (say 3A< with a fall = 2.20 points) -- well, her tech lead has been cut in half which allows others to pass her. No, the others are not THAT superior, just a coup[le of points here, a coupe pf points there, which is all that is required.
