Keystoner, there is no need for Andy to take another look. I already went back-and-forth with him about one hundred times on this issue. He sees what he sees.
Very true, and also agreeing with you that it does not really matter, the real question being which is preferable (which question you have already given your detailed answer to).
Nevertheless, I have two treats for you guys, which may highlight where we see differently.
First, please look at the three attached pictures, excerpted from the video, with the contrast increased.
To see something, you will probably have to click on each picture. These are three consecutive shots.
==> The first one shows Lee having completed what I call the single twist (same as
my picture # 1 from today I believe).
==> The second one shows Lee... starting to twist that first nip again, clockwise, i.e, starting the double twist.
==> On the third picture (blurry, sorry), he has completed the double twist, and is about to push the bight through it.
Second, if you guys have a media player, please take a look at
this excerpt from the video, showing exactly where I see the double twist happening.
[Apologies in advance to readers from the future, as I will delete this at some stage for copyright reasons, although I believe such an excerpt constitutes "fair use".]
If your computer doesn't play this file, you can download
PotPlayer (fabulous for PC) or
VLC (for Mac or PC).
Looking forward to your thoughts about what we're seeing differently here and why. I might yet rally to your camp.
@Keystoner, the most confusing thing about the southern hemisphere is that mirrors invert top and bottom instead of left and right.

Peace,
Andy
