call it tempered if you like. The purpose of the tempering is to keep it from getting stagnant, making sure it does not get too humid. Building Science site has scenarios they are blowing 25 CFM and calling it conditioned. If you have gable walls you need to insulate them also,].
I will look, I have some numbers for when I was keeping my place at 75, off the top of my head the attic did not follow suit exactly,it did not average three degrees lower.
SO it would sort of being like heating your house to 72 in the winter and it is only 68 in the basement
Malls with barjoist, built up decks, flat roofs are a very similar scenario, the space above the ceiling is a plenum but is really a sealed attic
