Hello,
I have followed the input data as written and i get the exact same results as stated in the table, respectively 7200 & 2970, so my guess is that somewhere you must have missed the units (Dimension, Material Properties, Loads or Constraint). FYI my model is made with 1 element and both (Simple & Clamped) solved at P=4. Also you have to model the curve in XY-plane, with the Y-axis as the symmetry axis. But based on your deflection i believe this is done alrerady. I can't open your file since i am on Creo 2.
Regards
