Dynamics CRM User Audit access - 4 hrs

I would like to know, if this is by design that dynamics CRM user access audit will be logged in 4 hrs only.

I saw message as below

"the user started accessing microsoft dynamics crm on through the web page or the outlook hoster. subsequent access by this user to microsoft dynamics crm may not be logged for the next 4 hours"

appreciate any thought if this is fixed or can change the value?
