Hello Dakka, after recently falling in love with Spartan Games' Firestorm Armada I decided to make a quick little tool to make handling the various percentages and restrictions associated with building a Fleet List much easier. After completing a useful version for my Terran Alliance fleet, I decided to expand it into a single file that accommodates all six of the core fleets and share it. This is not a substitute/rival for Army Builder and, if you do own that software, TheBlackOcean has a Firestorm Armada file in beta at the moment if you are looking for an all-inclusive application for fleet building and stat/rule reference. This simple tool here is exclusively for building a Fleet List and was created with the expectation that the user has access to the detailed information of their ships (which is available for free download from Spartan's website); this is just a calculator.
Here is the file:

I apologize for the barrage of ads on the download page but as it is a free-hosting site it was unavoidable. I hope that you guys find it useful and, as mentioned in the file, feel free to contact me with any corrections if an error slipped through.
