Hi -- Colin asked me to repeat on the list a comment I made at the Mic in the session today, so the idea doesn't get lost.

There was the discussion about when the circuit breakers should trigger for AVPF early feedback, and the comment was it should be done for compound packets containing SR or RR packets, but not for those that don't.

If something like the RGRP proposal is adopted, and in the presence of RFC 3550 report block round-robining, this will need to be more complex.  I think the correct formulation might be that you should respond to SR or RR packets that contain a report block for one of your sources, but not those that don't.
