Should I move to 2* kMaxDatagramSize?

 The timer duration, or Probe Timeout (PTO), is set based on the following
 conditions:
 
-* PTO SHOULD be scheduled for max(1.5*SRTT+MaxAckDelay, kMinTLPTimeout)
+* If less than 2400 bytes are in flight, PTO SHOULD be scheduled for

Yes, but the receiver needs to know the current.  Should I reference kMaxDatagramSize and call that close enough?  I'm fairly concerned that if that changes over the course of the connection, the sender and receiver will not act predictably.
