After having a closer look at this scoreboard, the left side has a farm that's too big
I play with WoF and it has the same problem, I'm always trying to own the biggest farm side of the WoF, as this makes it very easy to make a big farm. And if you get the chance to place a cloister or bridge to make the farm pass over one of the roads, you get an even huger field (sometimes I could get farms worth 250+ points with pig when playing megacarcassonne).
The City of Carcassonne has the same layout tweak.
An additional road or city that blocks the farm is missing on both this scoreboard, the city of Carcassonne and the WoF
Edit: Thanks to GQ11 mini expansion, the river source may be divided into two separate farms, avoiding this problem
