As part of my Nano One setup, I've mounted my G10 plate to Dual-Lock twice. For me, that's a lot of times, but presumably anybody using it as a release mechanism does so fairly frequently.
I was a little surprised by the positional accuracy I was able to get. After a number of tries, the best positional error I could get was about 0.03".
(How I computed this: The best I could get on left and right in the front was about 0.22" on one side and about 0.28" on the other. Averaging those tells me the ideal was 0.25", and so my error was 0.03".)
In terms of fractions, that's basically 1/32".
In a way, that's sort of accurate.
But then I hear people talking about moving their bindings 1/16" or even 1/32". That doesn't really seem possible if it's about the same as the inherent slop in mounting Dual-Lock. And it makes me wonder if being off center by 1/32" would be considered by some to be a problem, although I'm certainly not feeling anything on the water that seems "off-center."
The repeatability, however, seemed to be much better. Because the little mushrooms are discrete, there are certain position it wants to go to. On more than one try, I got 0.22 plus a few thousandths as my caliper measurement on one side, suggesting the repeatability might be as high as 1/500".
For a release mechanism, I guess repeatability is probably a lot more important than accuracy. What's really important is that once you get it somewhere that you like, you can get it there again.
Btw, I don't really have a "point" -- just some observations. Discuss or ignore as you wish!
