My personal thought is that in each case, it would refer to the Overload 
Algorithm(s) in effect at that node.

But that brings up a whole can of worms about interaction between 
algorithms..

If the Event package has set up an a-priori Overload  Control, and then an 
actual overload triggers a "feedback" Overload Control, how do they 
interact?  The max? the min? the "product"

Is that a can of worms we want to open at this point?
