I remember seeing comments that were roughly "it takes a month" and that seemed like a long time. This was a convenient opportunity to collect some hard data.
And, of course, it's still a matter of interpretation. I look at your plot and say, Yep, it should be mostly sorted in a month. Someone else might look at it and say, Looks like 3 days to me. Based on your plot, what do you say?
Also note that your oscillator was unplugged for a week or two, presumably after being on-power and in a stable location/environment for a long time. This is pretty much the best case. Most time-nuts buy oscillators of unknown provenance that have been off power for months to years, with (maybe) a brief power-up cycle to check them out by the seller, then shipped across the country or halfway around the world. Many of those will take much longer to stabilize than yours looks like it's going to take. (I hope you're still taking data -- it will be interesting to see if there are any surprise jumps or drifts before it settles down "for good," which happens more than occasionally.)
What do we mean by "unknown provenance"? I've watched breakers remove oscillators from equipment and toss them ten feet into a big metal bin. After sale at auction, the oscillators was poured out of the metal bin into a pickup bed and driven across town, where they were shoveled (literally, with a snow shovel) out of the truck bed onto a concrete floor. One of the nicer-looking oscillators was photographed for an ebay ad, and when one sold a random oscillator was pulled from the pile and shipped to the winning bidder. If a customer complained, they sent another random pull and when the first one was returned, it was tossed back on the pile. And this is in the US -- I've heard *much* scarier stories about breakers in other countries.
