Monitor and manage game stats

I am going to preface this question with the statement that I am a nerd that likes the occasional video game. Clash of Clans is one such game.

I have been asked to track some stats for my "clan." The attached workbook is a representation of some of what I want to do, but I am not sure what the best way would be to:
1. make it more efficient/easier to use and enter data,
2. track 2 different sets of data per "player" each time we have our "war"
3. display the data, especially text based data, in a format that will be easy to read.

If you aren't familiar with the game, here are a few things you need to know. Players join together in "clans" and have the option to participate or not participate in "wars" and can change their preference to participate or not at any time. In wars, the clan is matched with another clan and each player has 2 opportunities to attack the enemy clan. Each war, players are ranked in order based on a number of factors, but boiling down to how good their "base" is. Your rank can change every war as others upgrade their base and members are added or leave the clan. Every attack has 4 levels of success, measured 0-3 stars, 0 being a poor attack and 3 being a perfect attack.

I have listed the data I want to track in the column headings on the "input" sheet, but I am not sure how I can track 2 attacks separately.

Another important piece of data I need to track is if the player was MIA. If they chose to be in war by "opting in" but they failed to use their attacks or only used one of their two, I want to be able to track that. I do not want to track MIA's for players that "opted out."

The data I have to work from comes in chronological order. We usually have 25 players participate, so 50 potential attacks, and I get the data in the order that they used their attacks.

I know that this may seem kind of silly to some people (just remember that they track stats in baseball too, although you may think that is silly as well), but any help would be greatly appreciated.

Thanks,
Jason
