Batch Training (The Good, The Bad and The Ugly)

[DesertRose]

If we compare no batch to 2-10 batches.

After 60 seconds:

2	1.02767254972061
3	0.985794108773369
4	0.96419601647961
5	0.842511233639707
6	0.809886682621353
7	0.787635316056181
8	0.725540687970097
9	0.624656521911935
10	0.485888389876762

Meaning after 60 seconds only 2 batch production is ahead, and only by ~2.8%

After 90 seconds:

2	1.07140697286798
3	1.08663652712691
4	1.07784597069266
5	1.03953334109689
6	1.03076486879081
7	1.00244494770787
8	0.923415421052851
9	0.849421381590345
10	0.855485117783215

After 90 seconds 2 batch production is ahead by ~7.1%, 3 batch production by ~8.7%.

After 120 seconds:

2	1.09181637033674
3	1.12649376026016
4	1.13088261599208
5	1.13147699124358
6	1.13384135566989
7	1.10268944247865
8	1.07930705300764
9	1.0801167081955
10	1.05440758719945

This is what I found surprising. After just 120 seconds even producing Civilians in 10 batch sizes you are already head of producing them 1-by-1.

2 batch production is ahead by ~12.6%, and 3 batch production by ~13.1%.

After 180 seconds:

2	1.10904224897359
3	1.16689945242606
4	1.20032846736228
5	1.21690362218682
6	1.22988990026177
7	1.23128368774283
8	1.23040276261435
9	1.21621697818618
10	1.22489914591688

4 batch production and up is at least 20% ahead.

After 240 seconds:

2	1.12005300060407
3	1.1872998244697
4	1.22837249668105
5	1.25907655790822
6	1.2772006075362
7	1.29365142554231
8	1.30261196052646
9	1.30358913058077
10	1.30814403567772

After 360 seconds:

2	1.14110639562759
3	1.21895993515409
4	1.27224294299109
5	1.31293842431479
6	1.34318602533905
7	1.36823258770606

9	1.40154527962407
10	1.4115504443423

I imagine you would need to build additional training buildings sooner. 

I have updated the sheet with the table above and with a column how much batch production increases production speed, assuming a batch multiplier of 0.8.

2	1.14869835499704
3	1.24573093961552
4	1.31950791077289
5	1.37972966146122
6	1.43096908110526
7	1.47577316159455
8	1.5157165665104
9	1.55184557391536
10	1.58489319246111

I have not looked (yet) at how producing from more buildings with less batch sizes compares to less buildings with bigger batch sizes (but both having the same total production speed).

Interesting

I will try 3 by 3 then 4 by 4 and let you know

The bigger the batch the less flexible you are though

are we still talking about batches here?

Tbh. I didn't fully understand what each is doing here. But as I understand it, the pro of small batch is the units can get faster to work, the pro of higher batch sizes is the total train time decreases.

In this simulation a unit with total cost of 100 gets produced, gathers with 0.75 without ways to drop of, at different batch sizes from one cc. To account for the ways one could reduce the gather rate.

I wouldn't take any practical advice from this. Just spectate some games with good eco scores. This leaves out the timings of the next barracks which costs again.
