Primary objective - soak the opponent!

Relative wetness

This is a rather subjective means usually done by eye. Water fight participants simple do rough approximations regarding the amount of their clothing has been soaked through versus how much dry surfaces remain. In the event all participants appear to be fully covered with water, sometimes participants opt to wring their clothing as further means to show how wet or dry they are. And by the way our hall way looked when these two decided to end their war, I'd say it was a tie!
