Ten jigs from one drift is wild, but it makes total sense once you say it out loud. My question is what actually tipped you off to the drift in the first place, was it a test cut that kept coming out off, or did you finally just measure the fence against the miter slot with a dial gauge? And now that you're down to 4, which ones survived the purge and what job does each of them actually do that a plain fence setup can't? Curious because I've got a shelf of shame I keep telling myself I'll use someday.

The line about "most accidents happen on the boring ones" is real. I did the same thing for crane picks a few years back and the near misses always came on day 200-something when I got lazy on a lift I'd done a hundred times. You stop treating the easy stuff like it matters and that's when your hand slips. Keeping a tally sounds weird until you realize it's just a way to stay sharp. 500 clean is not luck, that's you actually paying attention.
