I've also just noticed:
Military strength rank says I am
Off: 429 better, 4855 worse,
Def: 307 better, 2389 worse.
There are ~3200 players and ~3400 villages on the server.
Lets assume Def rating does not count players/villages with 0 troops.
But how do you explain "4855 worse" in Offensive? What are those 4855 things?
