The first DC penalty is always 5 minutes, that's so if something does happen during a game you are not punished extremely - meaning that if you're bugged etc and have to leave the game or there is a game crash. The DC penalties increase in increments after that.

There is no way for the system to tell if you've intentionally disconnected or not, so the DC penalty is applied across the board.
