Well, there're two hidden assumption:
(1) The mrtts of the most recently acknowledged N packets without re-sending approximately reflect the current state of the network can we say rartt and rvrtt.

(2) For transactional communication, congestion control may be of little use. I mean the estimate is intent for long persistent connection.

While assumption 2 may be acceptable, assumption 1 is really a problem.
