Hi All, 

I ran Kurt Schraner's large coil in acmi pulling his coupling measurements from
his Excel spreadsheet. Kurt's test identified coupling measurements at various
turns (1, 2, 3, 5, 7.2, and 9) at four different heights. Kurt, you may notice
the height position is 8.858 instead of -8.858 as in your spreadsheet (this is
just a height relationship changed to match acmi's way of thinking). 

Single turns are no good (lot's of reason's such as meter measuring a very low
inductance and I believe the program cannot produce the correct dimension for a
single turn because the turn grows around the primary in width and the 2nd turn
is required to account for this growth via ID and OD - 2 or more turns are just
fine). 

I also put up Jon Rosentiel's data, Terry's, updated Marco's, my own, etc..
Marco's however shows a larger error which I'm sure is due to dimensions being
as was the case with my own coil for a while. 

Here's the data:
