"Average Stars Per War Attack" profile stat.

Details

1.) Only calculates war stars from your previous 5 clan wars
2.) War data over 1 month old is not used in the calculation (you must be active to keep this stat)
3.) Does not count stars achieved by hitting below your town hall level (If you only attack at your level once then it will mathematically weigh more, so don't mess up)
4.) Stars gained by attacking over your town hall level are worth 150% in value (If a th9 can 2 star a th10, they deserve 3 stars for that)

Number 4 also means that if you are forced to attack vs a bunch of engineered clans (I have no issue with them BTW), at least you get recognized for stomping a th10 that weighs like a th8 etc.

What would your number look like?

I think it should show all new stars from war. Also the player can choose in the setting whether or not to display avg war stars
