Is there even any way to know how often we should do it, or is it all guesswork?
No. Because the belts are rubber+fiber, making it really hard to predict precisely. Once a couple weeks should be good enough tho. You can also do it fortnightly if you print a lot.

OK, but where did the couple weeks number come from? Is that gut feel or did you arrive at it some other way? Or educated guess? If educated guess, I’ll still take it, as yours is probably better than mine.
I hate the way it reports the amount of improvement. Instead of saying how much improvement there was over the last setting, it seems to report the amount of improvement over no optical compensation whatsoever. The proof of that is that if you run two optical calibrations back to back, it reports the same amount of improvement for each.
Optical build plate? You mean the vision encoder? I seem to remember it saying about every 2 weeks.
Yes, sorry, I used the wrong term. I’ll change the title to make that correction. Thanks!

That to me is actually a good thing, so that you can correct mechanical issues (tension imbalance on the belts)

I have around 500 hours and ran in once around the 50 hour mark. I’m guessing I’ll run it again if I start seeing print issues?
Maybe it gives you advance warning in that regard. As I understand it, H2D monitors the resonate frequencies during calibration and uses that to determine when we should tighten the belts with a message to that effect.
From what I’ve read Creality K2 Plus offers something closer to actual automatic belt tensioning, but I don’t own one of those, so I can’t confirm.
Yes it does have that feature, but from my tests, it’s very much useless at least on the X1C. It would only start to generate a warning when things have gone very very wrong. Not sufficiently useful for better motion accuracy.
If only K2P had a better heat bed, it could have been the H2S that we all deserved 
If you own the plate, just do it once a fortnight, tension the belts every month and get on with it.
