Actually, like Chan, Hanyu does basic stroking into his opening 4S.
Hanyu does turning 3 into it.
As for their 2nd quad, Hanyu's RBO-LFI open choctaw step preceding the 4T is tricky yet it's far easier to execute/maintain speed than the LFO-LBO rocker turn preceding Chan's 2nd quad.
Chan does not do that turn directly into the jump, Hanyu does. Giving yourself 5 seconds after a single rocker turn is hardly more difficult than a choctaw directly into a jump.
As far as their 3Z-3S entrances, Chan's entrance with a flying RBI-RFI counter is much harder than the mini waltz jump pirouette Hanyu does. A flying counter requires much greater edge control and is a greater risk to a loss of speed.
Chan does not do that INTO the jump. He does it as an inbetween and then does crossovers into the jump. You're also leaving out the steps Hanyu does.
