If you aren't giving yourself room for expected and
-->unexpected<-- loads, you're doing it wrong.
You're using that word, I'm not sure it means what you think it means.
Over here in the real world, many applications (and notably web-applications) have one thing in common: They change all the time.
Your capacity plan from October might have been amazingly accurate for the software that was deployed and the load signature that was observed then.
Sadly now, in November, we have these two new features that hit the database quite hard. Plus, to add insult to injury, there's another old feature (that we had basically written off already) that is suddenly gaining immense popularity - and nobody can really tell how far that will go.
