How is 'Utilisation Excluding Changeover' calculated in the Theatre Utilisation Session Details table?

To find the session details table, navigate to Surgery > Theatre Effectiveness > Utilisation and select the 'Session Details' button. 'Utilisation EXCL Changeover ' is Column Y.

 "Utilisation EXCL Changeover" is the percentage of session used within allocated session time without changeover.

(Used minutes (Column J) / Allocated session minutes (Column G) *100)

This does not include early starts (column AA) or overrun minutes (Column Z).
