Topband: How do you count the turns on a binocular core?

[Kenneth Grimm]

*I recently decided to put up a gaggle of reversible two-wire 
beverages.  I looked at Vic Misek's book, checked into what ON4UN had to 
say about them, visited W8JI's site, looked at several other web 
postings and still have some questions about how to get them to work.  
One of my questions arises from an inconsistency in what the articles 
have to say about the very basic question, "How do you count turns in a 
binocular core?"

Joe Carr, K4IPV, on page 100 of his book, Secrets of RF Circuit Design, 
suggests that for a two turn winding, there would be two wires passing 
through each hole in the binocular core.  See **http://tinyurl.com/yhwqpf

**Mark Connelly, WA1ION, **in Fig. 2 in **his article "Remote 
Termination of Beverage and Ewe Antennas (found at 
http://www.qsl.net/wa1ion/bev/bev_remote_term.htm ) indicates the same 
as Carr, ie. two wires in each side of the core to constitute two turns.

John Devoldere, ON4UN, in his book, Low Band DXing, 4th ed. on page 
7-59, suggests that there would be one wire in each side of the 
binocular core to have a two turn winding (4 passes, 2 turns).

John's approach appears most logical to me, but Carr and Connelly seem 
to have come to a different conclusion.  Is theirs faulty thinking 
carried over from the toroid case or am I missing something very basic?
