 Group wait is the duration Grafana waits before sending the first notification for a new group of alerts.
 
-The longer the group wait, the more time other alerts have to be included in the initial notification of the new group. The shorter the group wait, the earlier the first notification is sent, but at the risk of not including some alerts.

 Repeat interval must not only be greater than or equal to group interval, but also must be a multiple of Group interval. If Repeat interval is not a multiple of group interval it is coerced into one. For example, if your Group interval is 5 minutes, and your Repeat interval is 9 minutes, the Repeat interval is rounded up to the nearest multiple of 5 which is 10 minutes.
 
+The maximum duration of the repeat interval is 5 days, constrained by the default value of the `notification_log_retention` setting in Grafana.
