It just barely needed a touch up. There was a tiny bit of red push and blue had dipped a notable amount at higher levels. Some of the grey scale had drifted out to 2-3 dE or so, pushed all levels back under 1 dE again. (Got everything except the 90% under 0.5 dE).
I went ahead and fixed the gamma curve a bit too, and then got the primaries back under 1dE (they had drifted out a little, but still were all under 2 dE).
Got the saturation sweeps a bit better than I originally had, and same with color checker. Had 1.8 dE average back when I calibrated it in January, this time when I finished it was 1.69.
Wow, I'm seriously OCD. I don't think any normal person could tell the difference, but I swear I can tell that I cleaned up that slight red push.
Anyway, this set doesn't have much drift at all once you've put a lot of hours on it.
I would say that under normal usage (not my crazy leaving it on almost all the time), that it would probably only just barely need a touch up every 2-3 years.

Yeah, probably a good idea. But for now I'm going to enjoy my freshly touched up calibration.
