Describe the issue: 

It is not clear whether users should change the virt-who interval from the default value and when users should change it.

Section 3.1 says recommended value is 2 hours.

Section 4.2 says says default value is 1 hour, and user should not change it unless requested by Red Hat Support.

According to the healthcheck report for a customer, it says default is 60 seconds, and recommended should be 900 seconds.  -> (possibly meant minutes instead of seconds)

According to the healthcheck report for a customer, the value should be adjusted after the bulk activities of provisionings and system registrations are done. 

Suggestions for improvement: 
* Confirm what is the recommended value.
* Add in info on when to adjust the value, for example after the initial provisionings and system registrations are done. 

Additional information: 
This issue was identified when researching for the My customer pilot project.
