Just as a bit of feedback, I think it would be great if umpires could record the details of combat resolution in a manner similar to the way "Command" displays it in the running commentary down the left hand side of the screen. By that I mean something like "Gadfly vs Harpoon. Base .75. Less .3 for SSkimmer. Less .15 for VSmall. Final .3 Roll .44 Miss"

You could just jot this down longhand or in a computer file and then reveal it at the end of the game.

You could also take a screenshot of key events, using something like Snipping Tool.
