QuoteThe Lugano emissivity settings have been independently tested with a finding that Levi's settings IR camera adjustments were materially low.
Which is part 1 of the issue.
Part 2 (which Levi and also, interestingly, randombitio here) did not understand, is to recognise that the report graph - for total emissivity - is possibly correct. I say possibly because due to Al translucency we don't known, and the real result could move in either direction from theory...
