Agree this is just a guess today, I have no idea of what is needed for a particular unit. My strategy is the following:
1. During phoney war phase, I am putting 0 for reinforcements & upgrades. My goal is to produce the maximum of units.
2. After taking casualties, i.e. active fighting, I am usually putting production of new units on hold and assign everything to reinforcements, upgrades and repair.
3. When I see the Upkeep value decreasing, I know I am in a good shape to go back to point number 1.
