I think they need to be very careful with this. If it is only kicking in for a couple of hours a day, then I would agree that it is no big deal. But if it starts kicking in for six hours a day, that would indicate to me that there is a real congestion issue and they need to split the node. Keeping a close eye on that type of thing and determining how often it is kicking in is too often, will be the real test.
