Of whom, one at least shouldn't have (2014), one won from one of the most forgettable and pointless fields (2018), and one did so jumping 'quads' that were never quads (2022).
None of these women was better than the non-Russian skaters they beat, apart from Zagitova on that particular night. All of them had the judges on their side who inflated their scores far too much, with 2022 especially you can reshuffle the top 3 in any order and make it make sense (and Valieva should have been hammered out of the top 6 after that free skate).
Not that you're wrong about the point you're making there, because none of this is relevant to how they're judged.
