How is the mean balance per week (Column 'G') calculated in the HSEView Demand & Capacity component?

Balance = Column F minus Column E

Balance indicates the gap between demand (additions per week) (Column 'F') and capacity (removals per week) (Column E).  The value is derived using the formula below:

Balance = F - E

If the balance per week is positive, we would expect the backlog of over target patients to decrease over time. This can be triangulated with the Increase in Patients Waiting over Target in the last 6 months (C).
