wind chill temperatures comparison : old vs. new formula

On November 1, 2001, the National Weather Service implemented a new Wind Chill Temperature index [N17], designed to more accurately calculate how cold air feels on human skin (see [HANDBOOK]). The new formula

wind chill temperatures : new formula

where WCT = wind chill temperature / oF, T = air temperature / oF, and V = wind speed / mph, replaces the old formula

wind chill temperatures : old formula

The young specialist in English Literature lectured me severely on the fact that in every century people have thought they understood the Universe at last, and in every century they were proved to be wrong. It follows that the one thing we can say about our modern "knowledge" is that it is wrong.
My answer to him was, "... when people thought the Earth was flat, they were wrong. When people thought the Earth was spherical they were wrong. But if you think that thinking the Earth is spherical is just as wrong as thinking the Earth is flat, then your view is wronger than both of them put together."

Wind chill temperature formulas comparison: the non-linear correction is versus wind speed, of course.

However, it should matter

at which rate wronger becomes wrong.
