Comparison of jump takeoff

[charlotte14]

Here's an analysis (with video and gif) of the toe jump takeoff of the "top 6," Yuzuru, Nathan, Boyang, Patrick, Javi and Shoma.

Jump takeoff concerns pre-rotation or no pre-rotation. If you pay attention, you'll see more and more skaters who can't perform full rotations in the air are now taking off with a sideway blade pick or push and pre-rotate 90-180*. Since ISU does not allow slow-mo review of takeoff (they do allow slow-mo review of entrance for edge calls), pre-rotation cheat has not been marked as < or <<. This is a problem that should be addressed by ISU. Before we have a resolution if ever, the judges should use GOE as a tool to punish pre-rotation and reward correct takeoff.

Looking forward to the edge jump takeoff analysis by the author in his/her next installment.

Some have pure Lutz and Flip, some have Floop.

Not sure where you're getting this idea from. Lutz and Flip can be done with no prerotation at all, as you can actually see in this video on Hanyu's Lutz and Flip, and the quarter turn prerotation allowance isn't something that exists. Jumps like toeloop, salchow, loop all normally have a half turn pre-rotation (although you can do less, quarter turn would be the minimum basically to generate inertia as you say). A half turn is really the allowance that needs to be given to every jump, although ideally I'd like to see the Lutz, Flip, and Axel done with less than that.

If I remeber correctly, no pre-rotation at all was how these jumps were first executed in the old times?
Recently so many skaters make use of pre-rotation in the toe jumps.

Back in the olden days, skaters didn't have to do triples, so there was less need to pre-rotate. It was actually common to see jumps with delayed rotation.

Dorothy Hamill had a lovely axel with delayed rotation, if I recall. When I get back on desktop, I'll try to find a link.

Ah here we are. My friends have stopped watching figure skating, but they all still love Dorothy.

ahhhh I can't help it, I've got to highlight more jumps that we don't see anymore. Nowadays it's all about a triple-triple-triple, but look here: a wally-wally-wally, with both arms over the head.

Shoma's Pre-rotation gets even worse at 4CC. After pre-rotating 270 degree his full "tappin" blade remains flat on the ice. You can see his forward take off in both 4F and 4T (use Chrome to play slow-mo and stop to verify it). With slight under-rotating, he only rotates 3 revolutions in the air.
