I didn’t address that point because it would seem extremely pedantic. To an economist, “an econometrician” is almost always someone who spends their time developing new estimators and proving things about their properties. The people who wrote the CBO report are very unlikely to have been econometricians according to nearly any economist. The CBO mostly hires applied people of various kinds, whether in micro or macro. They are users of econometrics, as we all are, but to say they are “econometricians” as economists use that term would be wrong. But that seemed like an extremely pedantic objection to the OPs point.
