I totally get it and the Mets agree. You don’t use an airport which is surrounded by jet exhaust and blacktop and 100% sun to verify dews. It seems like it’s you that doesn’t get it. The dew is representative of the environment. Why would my dew in the hills surrounded by grass , deep woods and country be as low as an airport? Why would yours be as low at BTV Mac? This is not hard to follow man
