I completely agree with your desire for relativistic schedules. Symantec indicated a LONG time ago that this is something they were seeking to implement and your reasoning has nailed it.
What you might find in here, though, is that some people are unwilling to talk about specific schedules and internal processes due to operational security concerns... it's trivial to look you up, figure out what company you work for, and then use that insider information against you.
I'd be willing to speak outside of the public forum, though. Drop me a message through my profile.
