For me it is another big analysis with very questionable scientific value.
The smaller issue is the definition of the jump's height. The correct one would be the raise of the skater's center of gravity. But to measure it would be very difficult without special equipment. If we name as the jump height the maximum distance between the lowest part of a skate and the ice we immediately penalize for no reason skaters with straight legs and skates pointed down vs. skaters with bent legs and skates parallel to the ice. Russian split jump will be the highest by the way.
But even then there is a bigger issue of how exactly one measures the jump height under any assumption. With frame by frame pictures it is impossible to get the exact highest point of the jump. Even if it were possible there would be an impossible task to point a strictly perpendicular line to white ice and to measure it. And they measure the distance in 0.1 cm? Just laughable.
Same as with another analysis on judges' bias the biggest issue, though, is conclusions made out of such analysis. Alina's 2A is smaller than Satoko's? Give me a break. But some people are very happy to immediately jump on this wagon.
