anybody knows where i can upload a spreadsheet that has the formulae already in? Would be helpfull i think for anybody to use. As far as the maintenance is concerned, I think leaving the maintenance cost as a figure is less complicated.
Go to the main Intel Forums page, and click on the Scenario/Mods Upload Category (first one). Upload it to the appropriate SE4 thread in there (probably Other Helpful Tools/Information).
As promised, the excel file that utilises the formulae mentioned in the thread. I took the liberty and put some sample data into it to aid the understand of its functionality.
