Good point, and I messed up.  A better way of putting it in retrospect  
is:

The delay based addition can't make the ISP congestion problem worse,  
because its Min(delay based, AIMD based) in prefromance.

It is an open question whether it can make the ISP congestion problem  
better, as at the common-points of congestion, the buffer sizing may  
be too small to provide a reliable indication of impending congestion  
in an ISP network.
