So I want to raise this topic to probably see if someone can actually answer this question.
vils gathering on Mills, estates, Rice paddies fields ects gather at different rate to account for moving around (effectively not gathering) bumping into each other and just bugging out.
Mills and estate - lots of moving around and bumping.
Rice paddies - bisically not bumping
Farms for native civs - no bumping
Fields - minor bumping, mid way between rice paddies and mills
What about haciendas? From gameplay it feels like there is no bumping, but I can’t really tell and how does this affect overall gather rate. I see some people saying that haciendas have lower gather rate then normal mills, but i suspect the actual difference is much less
