Town-growth

[AvG]

James,
I know we have discussed this matter before, but I am still wrestling with to high a towngrowth.
Results from my last experiment:
Settings in Pak-config:
growthfactor_villages = 400
growthfactor_cities = 800
growthfactor_capitals = 1600

Milano in year 1750:
Start 790 inh. Jan 958, feb 1207, mar 1424, apr 1454, may 1524, jun 1794, jul 2014, aug 2042, sep 2071, oct 2216, nov 2390, dec 2429
So in 1 year number of inhabitants tripled.

Since I do not know the formulas I have no idea what values to use in order to get a growthfactor_capitals for a long scenario (300 years)
10K inh in 1750 with growth of 3%/year gives in 2050 70 Mil inh.
Should I use for capitals 160000 i.s.o. 1600, or even better 300000

Hmm - that's odd, since I don't see town growth of anything like that. Can you upload a saved game?

James,
Uploaded a sve-file in simutrans-germany.com

I made some tryal run with different town_growth_factors:

Factors 40000/80000/160000 >> 1750/0 1812 inh  1750/12 1812 inh  so no growth at all
Factors 4000/8000/16000      >> 1750/0 1317 inh  1750/12 1317 inh  so no growth at all
Factors 2000/4000/8000        >> 1750/0  310 inh  1750/12   314 inh  little growth
       Second town                >> 1750/0  306 inh  1750/12   311 inh same little growth
Factors 1500/3000/6000        >> 1750/0  655 inh  1750/12   655 inh no growth at all
       Second town                >>            725                     725      no growth at all
Factors 1200/2400/3600        >>           1960                   1960      0 growth
       Second town                >>            539                     541      allmost 0 growth
Factors 1000/2000/3000        >>            639                     928      ~ 50%  (to much)
       Second town                >>            306                     457       ~ 50%     "
Factors 400/800/1600           >>            733                    1181        + 50%    "
Factors 1100/2200/3300        >>            541                     694       ~ 20%   From 1751 - 1757  979 inh  ~10%

Based on this outcome settings in my next scenario will be 1150-1600/2200
