Last thread I found on this subject is now 7 years old so I didn't want to necro it.
My question is how to calculate the time it takes to build a room because I have encountered two methods.
Lets set up the scenario:
We're in a Large Town (25 Capital/day limit) and want to build a small tavern (Bar + Common Room + Lodging)
Bar: 6 Goods, 1 Influence, 5 Labor, 16 Days to build
Common Room: 7 Goods, 8 Labor, 16 Days to build
Lodging: 10 Goods, 1 Influence, 7 labor, 16 Days to build.
Method 1:
Spend all the required Capital, wait 48 days (16x3), voila building done
Method 2:
Add up all Capital (45), divide by amount of capital available to spend per day.
1.8, or 2 days to spend all required capital. But buildings don't go up magically and require time to put work into, hence the time cost (duh).
So you spread the required capital throughout building time:
Bar: .75 Capital cost/day
Common Room: .94 Capital cost/day
Lodging: 1.13 Capital cost/day
This means that you can build the entire structure within 16 days (instead of 48) and still have 22 untapped Capital expenditure per day to build more rooms simultaneously if you so choose. After 18 days the tavern is open for business.
Now I think the method 2 is the correct one as it addresses the problem Method 2 doesn't: If I'm building a tavern with Method 1, it will take 48 days... if I'm building two taverns that are across the street from one another, it will still take 48 days and I end up with two taverns... but if I double the amount of rooms in the first tavern it will now take 96 days to build... which makes absolutely no sense.
