I noticed that when I use the Farm Stats, I get a variety of answers to the same question...
example... at one farm (36x36, 9-layered, edge-to-edge) I will plant a crop and then inquire how much I might get.
The responses are always different, and as much as 200+++ from high to low.
This is true if I ask for the current farm, or for all farms.
Weird. Just glad that the 49,900 +/- does not yield just a few hundred when I harvest
