I don't think we'll see any increase OR decrease in the actual numbers of SC assigned in most categories. What I think we'll see is a change in the start times so that we have a more consistent overlap of SC coverage.

How often do you see more than one short-notice call out at the same time of day (SC window)? I know (because of being on RES quite a bit) in my category that it is incredibly rare to see more than one at a time.

That being the case, they only need one "usable" SC per window as long as the overlap is sufficient.

But then again, that may just be my category.
