If you have ever wondered how a Packeteer PacketShaper allocates bandwidth within a Partition, or how Priority Flows compete with Guaranteed Rate Flows, then this spreadsheet may help you understand.  It is not a 100% accurate because the flows are in fact "tweaked" by the PacketShaper so not all flows are completely starved as abrubtly as this model shows.  However, it can certainly give you an idea of how your bandwidth can be affected by an increasing number of flows or a competing flow.
