How to edit unit upkeep

[SuperPM]

I found export_descr_unit.txt and I also found the unit I want to edit the upkeep for but I have no idea how to? I want to set it like 200 gold but I'm not sure how to do. There is a line called stat_cost which has several numbers but I don't know which one to change.

The upkeep is the third number:

stat_cost        1, 1150, 350, 250, 250, 1150, 4, 340

So, in the above example, the upkeep is 350 florins per turn.
