We just discovered our the numbers on the carafe of our coffeemaker at work are deceiving, to say the least! I'll pour in the top, what the carafe says "6," the coffee perculates and finished coffee drips down into the carafe, and it typically reaches just under the "6" line. That's okay, because I can understand how a small amount is lost. But we just discovered the "6" on the carafe means actually 3 cups (8 oz.) of coffee!!! What on earth is going on here? Why does the coffee in the carafe up to the "4" line in actuality only two cups? I don't get it at all. I looked at coffeemakers elsewhere in the office and it's the same. With those the carafes start at "4" but the lines go up at half the lenght - 6, 8, 10, 12. Explanation, please!!!
