The Building Calculator does not include on the display any data for Military Architecture Level:

http://prntscr.com/5n3ne1Is the calculator taking this data into account, and simply not displaying it?

Or is it not including Military Architecture bonus?

If calculator is not including Military Architecture bonus, how can I calculate the effect?

From How To Play:

_______________________________________

Military Architecture

A research with effect on Fortresses. Decreases the necessary time for building Fortresses by 15% per level and increases the garrison number by 10% from the basis._______________________________________

Does this mean I simply reduce by 15% the amount of time calculated by the calculator? Or is the 15% from basic time, and if so, how can I calculate my building time... Same question for cost. How to calculate correctly?

If I have correct formula, I can plug into spreadsheet and calculate myself. I don't trust Building Calculator without it including Military Architecture level.

I need to decide how much to invest in Mil.Arch / Arch / Builders Guild to get F9 in shortest time and best cost.

Thanks for any help/advice you can give!
