Unrest Revisited

[Nethog]

I was browsing through the modding.pdf file today and noticed the following two entries:

10.4 #unresthalfinc
The amount of unrest that cuts income in half. Default is 50.

10.5 #unresthalfres
The amount of unrest that cuts resources in half. Default is 100.

So in a standard D2 game, is the amount of income loss due to unrest a simple linear relationship? i.e. 0 unrest = 100% income, and 100 unrest = zero income? (all other income modifiers held constant)

Resource loss due to unrest was news to me. Does unrest actually reduce resources? and in the standard game is it also a simple linear relationship except 0 resources at unrest = 200?
