Yeah, they did a good job with her. She really had a nice set of programs for her first junior season. Eteri worked well on adios noniños and Stella still is my favourite free from her, and that was a 0+7 program. Definitely Gleikhengauz's best work for her after departure. Too bad she likes pop culture too much, i think lyrical is what suits her the best. I wonder what the program she ditched for twilight looked like.Yes, Kostornaya is an interesting example. Gleikhengauz managed to package her perfectly. Kostornaya was never one of the most technical skaters, She has a great pose, that is her strength, and sometimes people mistake that for artistry.
I remember her at Russian Junior Nationals 2017. She was a nobody and she finished 16th behind the likes of Kurakova, Nugumanova, Samodurova and Talalaikina. And while she was waiting for her (not so good) scores, the fans were all over Gubanova for autographs.
Then she moved to the Eteri camp, and they brilliantly transformed her into a star. That is choreographically genius. And it is an example of making the most of what you got. So Gleikhengauz and co certainly have some success stories that wouldn't have happened without their direction.
Packaging always have been their strength. It could be seen with Tursynbaeva for example. But their biggest flaw is that they were/are hiding their skaters' flaws, a bit too well. Instead of erasing them. Though it's the best strategy to answer the urgency of winning medals, it's a disservice for the skaters. Their flaws were pretty glaring when they went to other coaches and choreographers.
I'm a Zagitova's fan but i can say that it would have been pretty tragic if she went to another choreographer who would not spot her flaws right away and work on it. She was not a natural performer and her SS needed work.
