Completely agree. I do not understand the criticism of backloading jumps in a program. No one is restricted or limited from backloading but they choose not to do it. They see skaters like Alina and Evgenia doing it and being appropriately rewarded for taking the risk but are continuing not to do it. If Alina messes up one of the jumps in the second half of her FS, that would ruin the timing, speed and entries for the other jumps to come since they are all so back to back. She is taking a huge risk and if other skaters are choosing not to do it then it is their pill to swallow.
The tanos, I have a slightly different view. I think doing multiple tanos is okay if you do it "right". Maria Sotskova's tanos irk me to no end I hate her hand placement so I wouldn't consider it to be right. Now with that being said, I do not know if a tano is given credit simply for the fact that it is difficult to have the hand above the head during a jump or if it is supposed to also be aesthetically pleasing. I would say that it is given credit solely for the hand being above the head but someone can correct me if I'm wrong.
I'm sure a lot of skaters can backload if they train for it. If the system continues to reward it, backloading will become the norm, just like Biellmans.
