Re: Limited increase following EA Global—I would guess that EAG is most useful for consolidating people who already know about EA and linking them to each other in ways that increase productivity.
Re: different trends being caused by very specific things—I would guess EA as a movement only has a very small group of people who are fully aware of EA, interested in the various domains and ways of thinking. It has many more people who are involved in one sense or another—giving to effective charities, giving a large sum of their income, choosing to work based on effective cause selection, etc. These trends seem to suggest that EA is largely not sold as a bundle.
