Rooms in a specialist suite are not equivalent
A suite with six consulting rooms may have two in use every day, two used three days a week and two used only occasionally when a visiting practitioner attends. Servicing all six identically every evening spreads the same time across rooms with completely different levels of use, which means the busy ones get less attention than they need.
Following the roster corrects that without increasing the total time. The rooms used that day get the full task list; the rooms that were not used get a brief check to confirm they are still presentable and that nothing needs attention. In a suite of this kind the redistribution is usually significant enough to be noticeable within a fortnight.
