How much does the post-calibration vary if temperature and line voltage are stable? j...@febo.com said: > And just a note to those interested -- I'm targeting a modest update to the > firmware in the next month or so.

If you are working on the firmware, consider adding a time-nuts mode that also includes the post-calibration data. -- These are my opinions.
