Garrison vs. Public Order questions

1 unit of peasants keeps 1000 people happy

So If you have a population of 8000 you want 8 units of peasants in there for the full 80 percent bonus.

Since 20 units is max once the population goes over 20,000 you can no longer get the full 80 percent bonus.

As far as quality it does'nt seem to matter as far as I can tell

Right, thanks therother and Dorkus - the equations worked great. Therother, I plugged it into a spreadsheet and checked a good dozen points, everything was good to within what one can tell with the 5% rounding, including with an adjustment for Normal unit size. I even made a table - 10% to 80% X 1k to 32k population - and right down the 80% column is what you said, Oaty.
