That faster cooling rate is what your body feels in the wind. Insulate that cup and it cools down slower, same as you wearing a jacket. It is all related.
We agree, and yes, it is splitting hairs.
IMHO & IME - proper clothing negates windchill factor.
OTOH - riding into the wind will always slow you down, and with the clothes to keep you warm, you will slow you down more as it gets colder. So windchill factor is more of a drag-factor ???
