As to the Tx power, I was a bit surprised to see that was considered passing and do note a "unc." in the pass/fail column but saw no discussion on it in the report... but certainly that is not a problem for us to consider here as the error is potentially on the side of a tiny bit too much power.

The Nemko lab I've worked with in Canada has an uncertainty of around 1-2dB for their 10 meter site. It rolls up all the uncertainty in the site, antenna, cables, equipment, etc. Anything less than that uncertainty number means they have to put Unc. in the pass/fail, but it doesn't stop you from passing.
