As long as you're wearing wind-proof gear (i really hope you are if you're year round cycling) then the wind-chill/"feels like" isn't a good estimate for you... i don't use it because every mm of square skin is covered in something which cuts most of the wind out... the actual temperature is what i usually go by unless the wind is going to be horrible. If the wind is very strong then i might subtract a few degrees from the acutal temp but those feels like measurements are for exposed skin.
