Sister-in-law has three. Her friend has five or six, they don't stay still long enough for me to do a headcount. Her friend says two are three times as hard as one, three are five times as hard as two, but four, five, six, etc. are all the same as three. Because you now have help from the others.
I have no interest in finding out if she's right.
But I am willing to volunteer my services for the experiment . . .
