The average is very sensitive to how many small groups there are and how many of them we choose to count as an EA group. I don’t know the answer, and it doesn’t seem very informative about the value of any particular group. Perhaps it would be easier to talk about the average EV per participant-hour, and $20 of EA donations was our guess of that (though it will depend on the kind of participant—there are lots of ways of recruiting participants that I would evaluate lower, and some I would evaluate higher).
