Does the dark cup on the left of the brew strength selector mean strong or weak? Likewise - the white cup on far right -- is it weak because it is not colored in or strong because it is on the far right? Please respond asap -- I had a disgustingly weak cup of coffee this am and the person who made it insisted I am nuts because she put the dial all the way to the left for the dark cup which means strong. Are my taste buds off?
