If I ever drank coffee (instead of DMD) I might have an idea of how fast a coffeemaker dumps a specified amount of water through a filter. Let's see ... 2 GPM is 32 cups per minute, about a cup every 2 seconds - that seems like a lot for a coffee filter to handle, especially after some amount of clogging has occurred.
