How many people have noticed that when you replace a circuit with a
higher capacity one, the traffic on the new circuit is suddenly greater
than 100% of the old one. Obviously this doesn't happen all the time,
such as when you have a 40% threshold for initiating a circuit upgrade,
but if you do your upgrades when they are 80% or 90% full, this does
happen.
