I think it would be rather foolish to hold such belief because you are assuming Yu-Na and her coach are static or something and that they won't react to these changes and adapt. The 3A that Mao did on the Japan SOI where she UR, two feet, and stepped out will receive exactly 6.0 - 3.0 = 3.0 which is less than the value of a Double Axel. Better than before? Yes, but not by much. The < sign being shown will also likely reduce the GOE of skaters prone to UR, not to mention, the value of the Triple Flip has been reduced.
THIS.
Now I want to see Yuna continues her competitive career, especially with these new rules.
