How about a description of your arm 'lock'.
I too take pano shots hand held but end up cropping a lot of the top and bottom. Still a lot of shake so I try for higher ISO with handheld than what I use on a tripod. Less noise that way.
Don't forget that this was taken 3 months ago on December 13th, so it is coincidence...
Here's a single image from the pano - the EXIF is intact:
The original pano is quite large at 12117 x 3047.
I normally shoot ISO 400-800 to ensure high shutter speeds and clarity of the profiled foreground when it's darker and a longer focal length is employed.
The method I use to lock my arms - put my elbows right close to, but not quite on the sides of my torso, and stand in place. Then I simply pivoting enough to ensure some overlap from the previous image. Normally I'll shoot the series of images twice to be safe.
To draw an example, it's similar to how biathletes (ski/shoot) hold their arms when doing the standing shoot, as opposed to prone position.
I also have 20/10 and 20/15 vision (outcome of laser eye surgery). It's helped my macro work immensely too.
