Beaded isn't a coil so doesn't count.

The word "beaded" did not exist in my original posting... but there
it is in Cecil's reply, complete with the double that attributes it
me, so that Cecil can knock the straw-man down.

Ian, I think I corrected an obvious typo of yours. It
appeared that you had gotten off by one row. If that
was wrong, I apologize. Here's what you posted:

Choke Fmax Fmin Ratio
6t 1 layer 24 none -
12t 1 layer 15 31 2.1
4t 1 layer 21 34 1.6
8t 1 layer 12 19 1.6
12 32 2.7
8t bunched 6 36 6.0

There were six chokes. The fifth was bunched and the
sixth was beaded. The bunched ratio is 2.7. It seemed
obvious that you had made a typo in your chart which
I corrected.

Apology accepted. What you had missed was the statement immediately
above the table, that:
(the 8t 1 layer choke has two very small minima).
Therefore that choke has two lines of data.

The bunched choke is the one that has a Fmax/Fmin frequency ratio of 6.
A certain amount of mental gymnastics allowed you to claim that 1.5, 2.1
and 2.7 are all approximately equal to 2... so how about 6?
