That sounds amazing!
But one thing to note is that it'd technically be WR9 since Feliks' old record was 4.22, a former WR single. Feliks also got 4.29, and Sebastian Weyer got 4.32. If you're going by people, then it's still WR6, but by solves, it's probably not the fastest fullstep solve out of those.
