Claim 6:
7. The system of claim 6, wherein the processor determines the distance the shoe moves for every item added to the rack by:
receiving a first indication that a first number of items are stored in the rack;
in response to receiving the first indication, determining a first distance of the shoe from the front end of the rack;
receiving a second indication that a second number of items are stored in the rack, wherein the second number is higher than the first number;
in response to receiving the second indication, determining a second distance of the shoe from the front end of the rack;
calculating a distance travelled by the shoe on the rack between receiving the first indication and receiving the second indication by subtracting the second distance from the first distance;
calculating a change in the number of items stored in the rack between receiving the first indication and receiving the second indication by subtracting the second number of items from the first number of items; and
determining the distance the shoe moves for every item added to the rack by dividing the distance travelled by the shoe on the rack by the change in the number of items stored in the rack.
