Rate = Space Factor * Cost
Where Cost
in Service Areas where the number of Attaching Entities is 5 = 0.66 * (Net Cost of a Bare Pole * Carrying Charge Rate)
in Service Areas where the number of Attaching Entities is 4 = 0.56 * (Net Cost of a Bare Pole * Carrying Charge Rate)
in Service Areas where the number of Attaching Entities is 3 = 0.44 * (Net Cost of a Bare Pole * Carrying Charge Rate)
in Service Areas where the number of Attaching Entities is 2 = 0.31 * (Net Cost of a Bare Pole * Carrying Charge Rate)
in Service Areas where the number of Attaching Entities is not a whole number = N * (Net Cost of a Bare Pole * Carrying Charge Rate), where N is interpolated from the cost allocator associated with the nearest whole numbers above and below the number of Attaching Entities.
