# OgreDupe ELO system
# New rating = Old rating + K * (Result - Expected result)
# Expected result = 1 / (1 + 10^((Opponent's rating - Player's rating) / 400))
# Result is the actual result of the game (1 for a win, 0.5 for a draw, and 0 for a loss).
# K = how quickly a player's rating will change based on their performance. (We use 20)
