Reading about heat indexes, which reminds me to let you know that there are two competing units for how much clothing a person is wearing – the clo and the tog: https://ergo.human.cornell.edu/studentdownloads/DEA3500notes/Thermal/thcomnotes1.html
This seems sloppy, but if you think about it, the perceived temperature at infinite wind speed would also be infinite, due to ram effect heating and so on, so this actually has the correct sign for almost all wind speeds.
