During the transition to scheduled refreshes, admins must keep in mind the site default refresh rate, the refresh schedule per dashboard and the overall refresh capacity.
The default refresh rate is the rate at which most dashboards on the site should run. For Periscope's Automatic Refresh Rate, this default is normally every 24 hours. The rate should ideally be set in such a way that dashboard refreshes are able to run without being queued and waiting for other dashboards to first complete their refreshes. In general, there will probably be more dashboards and charts than can refresh every 10 minutes. If all dashboards and charts are set to refresh every 10 minutes, they will always be behind.
If the answers to these questions change, the default refresh schedule can always also be changed, which will update the refresh rate for all dashboards set to the default schedule.
Once the site default has been set, admins can then focus on the dashboards they'd like to set specific schedules for. Generally these are dashboards that need to be kept at a certain level of freshness.
Dashboard refresh rates should be scheduled so that there are not more refreshes than can be run in the scheduled time. Over-scheduling refreshes can cause a constant backup of the refreshes that are scheduled.
