You seem to have missed the beginning of the thread ;)
I'm not stating this number, Ajay at Broadcom is. He is saying that DBA
confers a 20 to 30% bandwidh advantage over Stat Mux. DBA is equivalent to
request/grant mechanisms of DOCSIS.

This was a mere example of my question surrounding the costs associated with
implementing support for a reques/grant scheme over using a default
statistical multiplexing mechanism.
