From what I've read -16.6(f) = frostbite within 30 minutes : -40(f) = frostbite within 10 minute : Any temp below -31 = frostbite but there is also a number a factors that qualify all those values. ie your age, weight and if the wind is constant. I have not found anything on the speed of the wind as it relates to the drop in temperature on exposed skin.
I'm not sure I'm reading your chart correctly but is there a time element on your chart or are all the values we see temperatures? Across the top I do see the x axis is a range of F-Temps but the y- axis isn't clear. Is there a Time value for the exposure to bare skin on the y - axis? I'm thinking your y-axis is wind speed?
I find your chart "right on" if all the values are just expressions of Temperatures. I don't see a -62 wind chilled temp in the light blue. The worst case I see in the light blue is the column for F 5 degrees, can get down to a feels like F -17 degrees.
