The STACKING RUN TIME concept to achieve desired RUN TIMES seems a bit clumsy. It can be error prone and creates some very larger reports and lengthy Calendar messages if you have many zones. If a new field called "Multiplier" defaulted to 1, with a range of 1 to 6 was added to the PROGRAM START TIME screen, a couple things could be done internal pragmatically. 1. use the "MULTIPLIER" to create internal stacked START TIMES (eliminates manual entries" OR 2. use the MULTIPLIER" to calculate the total run time for each zone. (Multiplier * Zone Run Time). (no stacked Run Times needed) Any thoughts??
