Hi, David,
You mentioned "per-AD" at the Admin Plenary open mike last night, and I wanted to make sure I understood your point.
I think you were pointing to the ballot display on https://datatracker.ietf.org/iesg/agenda/documents/, where there is a box for each AD to ballot on each document, and suggesting that maybe balloting for each area on each document might would work about as well, giving equivalent coverage while reducing the review load on each AD (except Jari, of course - there being only one GEN AD).
Does that sound familiar?
Thanks,
Spencer
