The problem is we really can't measure ground loss at the base.

Let me give an example....

A 40 meter vertical here, 1/4 wave tall of fixed length.

Four elevated radials had less than 40 ohms feed resistance. About a dozen 
buried radials had around 60 ohms base resistance.

Field strength was identical despite the resistance difference with the same 
length resonant radiator.

Others have measured the same type of thing, and it is easy to duplicate 
results like this.
