Document an explanation of the understeerCoefs values

[Fuzzwah]

I've got a fork that I'm working on adding understeerCoefs for more vehicles, and currently I'm just using a "best guess, then test" method. I'd really like a quick explanation of what the understeerCoefs values actually represent and possibly a bit of info on how the values for the current cars were settled on?

I am compiling my own list understeer values for cars I use. US Coef values are hard to come by. Have you had any success finding guidance on how to establish reasonable values?

Thanks

Has anyone figured out what the values actually represent?
