Hi Aerohead,
Apparently the ISO paper must have some other variables besides the absolute temperature that affects your calculated 18% increase in drag.
If the air drag increase was strictly based on temperature (air density), then the variation between 70°F and -20°F would be:
= (460°R + 70°F) / (460°R + (-20°F))
= (530) / (440)
= 20.5%
