Thanks for looking,

I exepected that to be the answer.  I did not see how the planner
could do its job otherwise.

However I was under the impression that delayed starttime was
something to recommend for clients that may not be available
when amdump starts or that couldn't be burdened at that time.
Yet the estimates are a form of burden too.

Why were you attempting to delay those DLEs?
