Im not sure it would be a minor error, but your flex duct in the reception office is about 10' and it could have been 1' long if you branched off the closest rigid duct.... I don't know if the test checks for these kind of efficiencies... The problem with super short flex ducts is that they are easy to miss when checking (triple checking) your vignette at end of the test...
