if you use near peak capacity for even a short term, other traffic is
rudely shoved aside.  Further, traffic does not return to its original
levels for a considerable period of time after each peak capacity
event.  If you set up conditions just right, not only will you not
receive "peak" payment from from the customer gaming the system, you
receive lower payments from all your "average" customers too.

Thats why statiscial queueing which penalizes unfriendly flows is a good
thing.

You could think of the unfriendly penalizing as an data version of a
'self-reseting fuse': disobey the rules (congestion control) and find
yourself cut off.
