            BOARD CAPACITY CONFIGURATION

                  N = # of boards

              B1=capacity of board #1

              B2=capacity of board #2

              B3=capacity of board #3

              B4=capacity of board #4

              X= (B1 + B2 +B3 + B4) -1

  Y= (B1 * (N > 1) + B2 * (N > 2) + B3 * (N > 3))

              Note: True =+1 False =0
