Hi all.

Well, actually I recall you should could the number of "highs and low" but as
fullwaves: that is, one local max (high) plus one local minmum (low) counts
together as ONE. For instance, if in the first ringdown you can count 5
"sines",
than K = 1/5 = 0.2. This has matched very well my simulations and measurements
with Thor and my previous TC.

Count the number of highs and low peaks in the first ringdown.  I got 10.
The coupling is one divided by that number or 1/10 = 0.010 in this case.
It's John Couture's method but I think that is how it is done.  It seems to
work very well!
