I just love Gracie's jumps and think she is very special. But I don't know what her jump height or hang time would be. The web site on this Sami says she exceeds at times .72 Not sure what that means and if your statement about Sotnikova or Gracie is true or not. Does anyone know what their jump height is? Anyone can shed more light on what .72 means that might help. In the end, I am not sure height maters as much as performing jumps in a competition. But back OT, I am sure that having Hanyu under the same roof will inspire this Sami to go for quads even more.
