Take a look at a few things that might make your war clan management and attack planning a bit easier.
ClashTrack explains this very well. But, I will break it down a little bit here.
What is it? Your War Weight is the factor that supercell uses to calculate a "fair" matchup between 2 clans.
How do you calculate it? The easiest way to do it is to open up a challenge. Ask a team mate to scout your base and click on one of your gold storages. Take the amount of gold reported in your storage tank and multiply it by the number of storage tanks you have and once more for the TownHall. For example, a TH9 might report that the gold storage tank reads 13,400. Multiply 13,400 x 5 = 67,000 / 1,000 = 67.
Your base war weight for this particular example would be 67.
What is the point of doing this? 2 Reasons. For an arranged war and for clan management. Professional clans keep track of all of their team mates war weight including information such as hero strength. By keeping this relevant information on hand it is a hell of a lot easier to determine if a new addition to your clan could be a liability or an asset.
