This gauge reports the average roams per second over the previous 5-second interval within a specific mobility network-id, rather than the system-wide figure. Admins use it to see short-term roaming bursts scoped to one mobility group, which is useful when different groups serve different buildings or floors. For example, an unusually high cwdsiRoamMblGrpStatsFiveSeconds for one mobility group during a shift change would point to that specific area experiencing heavy client movement.
