Always the case which is why they are called static curves.

Nick and I have no disagreement there. The issue we are discussing is the 
effect of shape.

Always. That is why in doing comparisons of parameters we would like to 
reduce the number of variables to see the true (or as nearly true as 
possible) effect of the parameter under consideration.

That is always the problem - fitting the boat to the paddler. Some believe 
the paddler should learn to fit the boat. Some believe the boat should fit 
the paddler. Some believe the boat should urge the paddler to learn more. 
Some believe that not all paddlers want to learn more.  If I had the answer 
I would be rich. Well, maybe not rich. Just better off.
