Great that you picked Carolina to demonstrate, because she is the epitome of beautiful and correct jumps and no one can fault her technique. Now if you actually watched these clips that you presented, you will see that her Loop and Salchow took off facing forward, and had exactly 2 1/2 rotations in the air. The Lutz and Flip were exemplary and had something like a ~45 degree pre-rotation so not three full rotations in the air either.
Honestly Gracie seems to stick out to me as someone using very little pre-rotation. :yes:
