What I have found is a bug on the Logistics math.
So.
T8 the Depot ends with 27365tons. It had just finished the Airfield lvl 2 and order is given to build lvl 3 on this turn.
T9 the Depot starts with 27365tons (thats the number in the brackets).
The Depot gets delivered 5119tons.
So it would have without anything sent out, 32484tons.
It ends up with 30457-32484=2027tons less. But it only lists 918 as being sent out.
So whatever the matter, the math ain't mathing. I'll also show below the construction from 1→2 (you may notice it takes like - forever...as a sidenote) and costs bazillions more, but you also can see the logistics accountant error occur (e.g. T5, T6).
As said it is heavily edited but I don't see how this would harm the math - it seems related to the Airbase construction which I was looking into (see the following info below the end of the Bug Report).
END OF BUG REPORT.
=============================================================================
I was originally trying to figure out...
- How much freight it costs to build/upgrade Airbases.
- How much time ittakes to build/upgrade Airbases.
- How the "size" of a construction unit is impacting the construction speed (I buffed a battalion in this second round of tests (see attachement)).
In a previous run with the ragularly sized construction SU I found these numbers:
NOTE: I did only look at the "Sent Out" figures in these test!!!
0→1: 250tons(village)-284tons(field)
1→2: 1000tons
2→3: 2250tons
...but I also used some adjacent/other hexes nearby, so not that exact same one.
So, before I have seen lvl 2→3 take at least 2250tons but with the regular sized Construction Battalion, taking several turns. While the buffed SU took just 1 turn as in the bug report shown (which seems reasonable). Meanwhile, the same massively buffed Battalion trying to build from lvl 1 to 2, seemingly was completely incapable of doing so as you can see in the following. And btw. by taking that many turns it was consuming ~2250tons (again, only looking for the "Sent Out" figures!!!), a number as mentioned before I had found to be the case for lvl 2→3. WEIRD! Background for the math:
The HQ consumes ~32tons. It is in Horse range so this gets to 32x1.5=48.
The SU (buffed) consumes ~42-50. Depending if at the Airfield or at the HQ due to horse range this number varies obviously, that's why in T3 above we have 91 and T4 we have 116, since T4 the horses needed to be fed ~45x1.5+32x1.5=115.5tons.
