I think it's the steps. I should rewatch but IIRC the required connecting steps/footwork were not really there... And we all know judging panels can be quite inconsistent when it comes to this particular requirement so...Some judges did give Mikhail's 4Lz 0 GOE? Maybe there wasn't enough steps before it or are they watching something else?
Still, he ended up with +GOE overall so he should be pretty happy. The jump itself was a real beauty.
