Hi Stuart,
There are some things about which I must voice my opinion.
Some of the comments you made made reference to vulnerabilities of positioning above the shoulder (due to the location of the elbows) are absolutely incorrect.
You wrote: "Having the elbows up as you do in the photo's above serves no purpose other than to increase your vulnerability for no gain."
I write: This is incorrect. Actually, having your elbows like that keeps your arms OUT of the normal arc of a blow when you are out long range. Not to mention the fact that the force of the blow is significantly increased as are the options for targeting you opponent.
You wrote: "I am at a loss to explain how you can justify having your elbows up based on both my evidence above and the fact that in no manual is this position you have chosen shown. "
I write: "I am not saying that these are all "guards" as I am quickly just glancing around, but I see some "over the shoulder activity" going on in these images...."

"In practical application - sparring - it seemed that the ON-the-shoulder position left your left forearm in a position for easy exploitation to a quick downward cut from an OVER the shoulder or head position. "
This is absolutely true. I have never been in a guard as John depicted -over the shoulder or, more to my personal liking, over my head and been struck by anyone on the elbows. NEVER. I have been hit plenty of times in training due to a combination of skilled opponents, dumb mistakes, and bad luck, but never in that guard. I have sparred multiple opponents many, many times and this guard as John has depicted is TACTICALLY SOUND. There are images showing it.
Looking at the tactical soundness of the on the shoulder.... I have seen people in the on the shoulder guard get their forearms struck as their arms lay in the natural arc of a downward swung sword when at long range. I think that that position may have applications for counters but the dangers of staying in that position seem a bit too high.
Now as I said in my earlier post, when BOTH parties use that guard, it becomes MORE viable. If one does and one doesn't, I'd prefer to be the one who doesn't.
Just my two cents.
