I doubt the judges are basing their opinions on a former coach's rantings in interviews. But I'm sure there are some judges out there that have outdated ideas of how skaters and dance teams should look (I'm sure there are also judges who dislike C/B b/c of their height difference).There's nothing to be done about it unfortunately. Krylova is so many miles away in Russia and she's still essentially body shaming her former student in the press.
But H/D are not at the same level as P/C and it has nothing to do with the size or shape of their bodies. Judges are looking for effortless flow (and that's true in all disciplines and levels) and H/D's skating does not look effortless. They have almost a 'freestylers doing dance' look about them.....i.e. powering through. They have great power and edge quality (why their RDs score so high) but so do P/C, who also have better overall quality, plus more ability to actually dance to a rhythm. And H/D have had some not-so-good programs over the last quad and a tendency to make significant errors at critical moments.
