Then we'll probably have to agree to disagree :)

Not so!

If you calculated the power density you would expect to see at that 
range from an isotropic radiator in Free Space - one which radiates 
uniformly in all directions - then apply the predicted EZNEC dBi figure, 
it should match the power density you measured.

As I see it, it's not a problem with EZNEC, it's how you define the 
reference power density; and your definition seems to be out of step 
with all the engineering references I can find.
