It's kind of verbose but I believe that actual output port
implementations typically provide for directly streaming out a packet
even as other parts of the packet are still arriving at the switch,
particularly in cut-through routing, or just sticking it in a queue
for output later if the port is busy. Do you have any suggestion for
better wording?

That's a reasonable point. Maybe

   3.2.1 Optimization for Change to Lower Priority

   3.2.2 Optimization for Change to Priority Only

Sure, that seems like an improvement. Might also be good to say "time
interval" instead of just "interval".
