     4-2-4b – Eliminates the use of double zero (00) as a uniform number option in order to eliminate confusion surrounding the signaling of “00” and “0”. Additionally, many electronic scoring systems do not have “00” as a number option.

This is a more appropriate position and transition for line judges.
