Ordinarily “the guys in the fb group” and “credibility” aren’t closely aligned in my mind. Maybe they’re right, but I can’t think of any good reason why there would be two different scales?The guys in the fb group are definitively saying with hood open is a different scale than with hood closed fwiw
However, I could see how the time difference between measurements might cause later measurements to be higher, due to fully draining the galleys.
interesting…
