Simple Vault Question

[groovdog]

Have read as much as I can find but its probably buried in an older thread and none of the spreadsheets have been updated that I can see. What are the upgrades past 10mil, would pref amount, expansion cost, expansion time if you can give it. Thanks in advance.

I think the below is the upgrade costs and I believe the expansion time is one week for all of them, but I could be wrong there.

Cost > Upgrade
3m > 15m
5m > 20m
7.5m > 25m
10m > 30m
13m > 36m
17m > 42m
22m > 48m
27m > 54m
30m > 60m
33m > 66m
36m > 72m
39m > 78m
42m > 84m
45m > 90m
