Subject: [quicwg/base-drafts] Congestion control during application limited state (#2554)

The text in recovery draft 19 says "The congestion window should not be increased in slow start or
   congestion avoidance when it is not fully utilized". This is a deviation from how congestion control works in deployed TCP implementation. We need a crisp definition of what is meant by "full utilization". I also have concern that this will make QUICs performance for bulk transfers poorer than TCP because application I/O patterns and scheduling of the sending thread will affect cwnd growth. After making the definition crisp and consensus that we need to include such a provision, the pseudo code will need to be updated to handle this as well.
