Another view is contained in the Dayton 2004 talk given by Rudy, N6LF.  See 
figures 21 & 22 and the associated text in
http://www.kkn.net/dayton2004/HF_vertical_ground_system_design_N6LF_Dayton.pdf

Depending on radial length, the total feedpoint resistance can be above or 
below 36 ohms, even with 128 radials.
