Bear in mind that regardless of the goals (in other words you don't know that a velocity of 40% won't give you a response time of .5 seconds).
The essential metric is the importance level. In period 3, you are essentially saying that when your system gets busy, Infoprint simply isn't that important to help meet its goals. The change from Importance 3 to Importance 5 shifts the degree to which WLM will help the service class period in meetings its goals.
