Well, several days would be a good time frame, I think.

I agree.  However, my production sessions normally run for several
weeks, and sometimes for several months.  I think at least some part
of the Emacs users, particularly those who don't track development
branches, have long-lasting sessions.  We should have statistics from
these long sessions as well.

I think your data is sufficient for now, we just need it from more
users and for longer times.  Maybe later we will have insights that
will help us identify additional data to be collected.

Thanks.
