I should have posted the size I measured, it was about 2 - 3/4  inch 
mean diameter.

Ratios traditionally are used to compare the same "units". If "d" 
is in inches  "s" must also be inches. Translated to turn to turn 
spacing for 2-3/4 in diameter:

s/d ratio.5 = turn to turn distance approx 1-3/8 inch  for Zo 1280 
ohms  Vp= .42

s/d ratio .75 =   2-1/8 spacing for  Zo 1060 ohms Vp= .55 

s/d ratio 1 = 2 -3/4 inch  for Zo 930 ohms    Vp= .63
