So we’re past 4.6, past 5, now we’re past 7 and have arrived at the worst possible number of 8.

I’d agree that 4.6-5 is good, and in my experience, out of 7, there are always a couple of non-participants, so it always wound up being more like five active participants anyway.

Full disclosure: my wife’s work has took me and my family to Hong Kong at the end of January, and we’re just returning to the States next Monday, so for the better part of the last four months, I’ve been the non-participant.
