Perhaps in case you want to allow some excess burst, but not shape to that
all the time!
Just a thought... But yes, if you are going to set Be = 0, then it really
doesn't matter which method of shaping you do, because your average and peak
will be the same.

Subject: RE: shape peak ans shape average
When we set shape peak with be 0, we get the same result as shape average.
Then I think shape peak can do everything shape average can do. Why do we
need shape average?
