Looks good. You can track revisions so it should be simple enough to fix if someone makes a mistake inputting data, though it is also a good habit to save a copy to your machine before making any edits.

What's the decision on how scoring will run, and what missions will be used? A modification that may be useful for the first round or two is to use 3 objectives instead of 6; if you want to use Maelstrom, then you can just modify like you would for a d3 roll on how objectives count. I like the idea of bonuses for batreps as it makes it a more connected event instead of a string of games.
