I have found that the best way to follow loses is from the OOB and total from one turn to the next.
turn 12 SHC 4,500,000
turn 13 SHC 4,400,000
turn 12 SHC losses 2,350,000
Turn 13 SHC losses 2,550,000
Basicly lost 200,000 but gained back about 100,000 from normal replasements.
Turn 14 you will recieve 110,000 ish in replasements instead of the normal 100,000 because some of the "losses" as stated are disabled.
Looking at a single turns snap shot is really not that helpfull. You need to look at the trend of the OOB's and losses and destoryed units(vs Humans).
As long as the enemys OOB is trending down your doing good.
Manpower is really the only bottleneck in the game for both sides. Armaments are not an issue for anyone anymore unless your doing something very wrong.
