By the way, the Rep -> Mon -> Theo switch only works if you have so much stock that after jumping, your upkeep is so high it is no longer worth spending any turns. Generally though, this is not the case if you are not a techer (only techers have small land sizes), and your income is still more than your upkeep all the way to the last turn of the reset. If so, switching is generally worse off, because if you didn't switch, you would be producing max income every turn until end of set.

To determine if switching is better, you have to spreadsheet it out, and make some estimations about your income after switching and after jumping, as well as the rise in upkeep during the jump.
