I saw analytics, but I made a change under the personal experience. When I play as a Zebasi, I always saw 6-8 tiles of crop on the Zebasi's spawnland. And I saw a lot of similar situations at the other players.
Ah, that makes sense, but that, according to James, is b/c -Forest -Mountain leads to more Field tiles (and more Farms), and -Fruit leads more of the field tiles to be farms. I think that the Wikia currently goes by what James wrote, though!
I'm trying to say that you are right in that Zebasi gets many more Farms than usual. And James' analysis explains why. And James' analysis is pretty autoritative, as it's the source that the entire community has used since it came out.
