Granted you will indeed lose more heat when it's windy but a windchill chart is really kind of meaningless as it pertains to objects that are either ambient temp or protected from the wind like a body in a windproof jacket.
Once, however, at about -30F I hopped on my snow machine and blasted across a small lake at about 50mph for about a minute. My entire face was flash frozen, superficially and I got a scream as the door was opened to the house where people quickly took me to a sink of warm water. THAT was a case where windchill was very meaningful.
Ok, then that one time your face had no protection but the rest of your body did. Your face was naked.
