Does anyone here know how exactly the economy score is calculated in Seven Kingdoms 2? I was playing one of the training missions, building marketplaces and factories, and my economy score went to the 130's, only to go down to 80 or so without any interventions from me...
Any ideas?

It doesn't explain anywhere in either the tutorials or the manual how the scores work. It's a huge, maddening oversight. From the first score-goal tutorial onwards, they are all very frustrating. You can own everything on the entire map, make hundreds of thousands of dollars a year, have camels running all over the place and an army the size of a small planet, and still the score will make a mockery of your performance.
I just hope the actual game isn't so score-obsessed.
