Advanced Crop rotation question.

[Infinity-Production]

Okay I am wondering if each map tile get their own separate counter for crop quality growth.
for example if my crop rotation farms center is where 4 map tiles are meeting, can i plant a crop, 4 times and get 4 different qualities if i plant them on each map tile?
Instead of waiting 5h between each planting season.
Or does only the 5h count for improving the crop?
I was thinking about dividing the map tiles with a 3 tile broad road with a granary in the center.

The number starts varying right away, but you're not likely to see a different quality for several tiles. It takes approximately 500 tiles to get a completely random number. Same goes with the "5 hour" rule. If you're thinking of doing something within the same visible area, you're not likely to get much, if any, improvement, and as much chance for it to slide down a point or two.
