Humidity calibration accuracy

Has there ever been a follow up on this (and similar threads), where feedback from Bosch was promised by Ruuvi?
I got three tags a few days ago, which read ~72% (OK), ~67% (errr, maybe?) and ~61% (just… no) in the same saturated salt environment. I can of course just offset them, but I am wondering if these even get a cursory sanity check before being sent out.

In comparison, the temperature and pressure sensors on the three tags are a lot more reasonable, much closer together, and generally a lot closer to what I consider “true”.
