Simple Excel sheet
- Load spreadsheet.
- Plug in the relative ratios of missile usage and the costs of each missile.
- Read off the percentage of your ordnance production that should be dedicated to that missile to have approximately the same completion date for all missiles.
- Praise NihilRex for his laziness and spreadsheet uber-skills.
Thismissile(Ratio*Cost) divided by sum of all (ratio*costs) if you want to make your own.
