It's like saying "when does Kolyada land 4Lz" when he landed only couple times.
I do believe both Kolyada and Tuktamisheva land pretty clean isolated 4Lz or 4T jump in practice. Kolyada even managed to land some in competitions.
Trusova too may land four may be five perfect different quads in practice. So?
