Bandwidth Reservation/Limit per WAN

Following post may answer your question:

Group Bandwidth limitation clarification

Is the group bandwidth limitation applied dynamically? Is this rule applied always, or only when concurrent connections occur? For instance, say I have assigned 50% to managers, 30% to staff, 20% to guest. If no users in the first two groups are connected, how much bandwidth will be available to guest? 20% regardless the fact no usage in Manager and staff groups?
