I've noticed that there is a field called 'Evaluation Interval' on activity sets which is set to 4 hours by default. What the heck does this mean? I know there's sometimes a minute or so delay between when a parent activity set is closed and a dependent child activity set is spawned based on it's trigger condition of the parent set being closed, but I've no idea where this 4 hour interval comes into play or why it matters. Also, so far as I can tell when the LE activity set engine / workflows come into play there's a 30 second or so timer before it makes another check on whether or not an activity should fire.
So...
Why is there an 'Evaluation Interval' option on an activity set if the evaluation timing is already being handled in the workflow?
If I change an activity set's evaluation interval to 1 minute what happens?
If I change it to 48 hours what happens?
I'm sure there's a good reason for it, but I can't figure out what that might be based off of the documentation noted below.

Note: The Evaluation interval field is not revealed by default. This field works with the Max activity countfield on the Activities tab under Workflow Properties. See Workflow properties . If you reveal the Evaluation interval field with the intention of changing the default value (four hours), use caution. Frequent updates mean that more events fire and could cause your lifecycle event activity sets to cancel before the Lifecycle Event completes. For workflows associated with Lifecycle Events, the value of the Max activity count field has been increased to accommodate long running business processes that contain multiple workflow activities.
