 ## Congestion Avoidance
 
-Slow start exits to congestion avoidance.  Congestion avoidance uses an
-Additive Increase Multiplicative Decrease (AIMD) approach that increases
-the congestion window by one maximum packet size per congestion window
-acknowledged.  When a loss or ECN-CE marking is detected, NewReno halves
-the congestion window, sets the slow start threshold to the new
-congestion window, and then enters the recovery period.
+Congestion avoidance uses an Additive Increase Multiplicative Decrease (AIMD)
+approach that typically increases the congestion window by one maximum datagram
+size per congestion window acknowledged, and MUST NOT increase the congestion

I don't have a strong opinion on this, but I see @mirjak point.  If we're going to keep this, I think we should be clear that this MUST NOT only applies to NewReno.
