Okay, it sounds like you are closing in on the issue. You are using a loupe, but from your description is sounds like a jewellers loupe rather one you can place on the screen. Is it? The latter will be much easier to use.
Finally!

Yes, it's a Bausch+Lomb loupe that I had from my watch repair days. Not sure where I'd find something else.
I do suspect that the fact that I had the gg wrong way around means that the thickness of the gg is what is impacting my focus.
I've also sorted the bed scale markings to use.
Thanks Pete!

Weird title, but hopefully the link works for you. There are much cheaper ones out there.

I use an inexpensive Carson, as mentioned earlier. You can get them from amazon.
This one is very large, 4.5x - barely fits on my ground glass :
And this one is way smaller, and 10x.
I usually use the giant one, as it is easier to see and use - and both are ~$10 each.
I have good results from both, I rarely ever miss focus.

Thanks Pete! Boy that's a monster. I'm hoping that sorting the gg and the bed scale will be enough to allow me to focus with my little 4x B+L loupe. If not, maybe I'll try a pocket magnifier that I got to use with the Mamiya 645 and the waist-level finder.

Just clicked BUY IT NOW for one of those. Should be easier than using the little B+L 4x.
Thanks Paul!
...and the money keeps draining...

I think that should give the correct results. I think that the modern lens will have much more contrast and, possibly, greater sharpness even against a Nikon lens. Also I would suggest the large format lens will be designed for a larger circle of diffusion in terms of definition. The Stroebel book is a little confusing on this subject but I think you have everything in the right places now. Hope you are happier with the next shots. You should get better results.

I should get the larger loupe tomorrow but I'm not sure I'll be shooting any test shots tomorrow...
[Sunday edit] well the large loupe did indeed arrive yesterday and while not quite a large as the Horseman shown in Pete's link, it is also pretty huge (and won't sit flat against my ground glass). I suspect that's OK since it doesn't focus for my eyes when flat on a plane anyway, I have to hold it about a half inch above the surface.

Boy, that loupe has worked great! Too bad I left mine up on the mountain yesterday after focusing...
It is possible that it will still be there as I had driven to a trail head off a main parking lot (although there do seem to be large numbers of mountain bikers who use the trail).

Turns out I also ordered the 5th edition to save the cost of buying the newest (6th).
