That is, a non-linear change. (The type of change, Simmons says, that the Hutchings factor specifically means to help.) It sounds like you haven't run into this phenomenon.
I've seen this happen at very high altitudes in my region on sunny days, about 1/2 or 2/3 stop, and more noticeable the more complete the shadow is.
