Yes. On one hand, people overthink the angle thing, what matters is how often we sharpen, not how perfectly we sharpened last year.
I go entirely by feel. It's very easy to feel when one has slipped back to the point where the edge isn't making proper contact, or when one has slipped forward to the point where digging into the stone is an immediate risk. The sweet spot is somewhere right in the middle between these extremes.
I work in a quiet room (other than the dribble of the faucet). I use an Atoma diamond stone to smooth the surface of my Shapton Glass stones frequently, often between knives. Perhaps I secretly want to actually wear out a water stone in this lifetime. More likely, when the stone is very smooth it gives very good tactile feedback as to how the knife is riding. A just-polished stone is like waterskiing a glassy Adirondack lake at dawn.
There is the potential for a feedback loop, here, taking my knives off course: The feel each time I sharpen has everything to do with how I sharpened last time. My chef's knives may have drifted, while for some reason my cleaver sharpening is spot-on.
Further evidence for this theory is that I'd already noticed I can get the 8" Fujitake chef's knife sharper than the 10" Fujitake chef's knife. In both kitchens. I'd always assumed it was something different about the knives, but this could be a reproducible experiment coming down to how I hold each knife as I sharpen.
A variant on your theory: While the VG 10 core is the same, the cladding varies on the different knives, and how straight each edge is. Both of these would affect the feel while sharpening. I go for "what feels best" while sharpening (an apprentice Japanese woodworker asks how to cook the rice for rice glue? So it tastes good), but this may serve me better on some knives that others.
There have been many reasons I've craved a good microscope. This would be one. A really sharp knife is actually more serrated than a dull knife. Whatever we imagine, we're all really just using bread knives.
