@pinskia in general, I'd expect a project with 4 maintainers to take about 4X hours per month from all the maintainers combined, but it usually doesn't slice evenly that way.
@pinskia oh, also: I think there is a difference in kind between being a *contributor* (especially a one-time contributor, like doing a bug report) and a *maintainer* on a project.
@evan Also when reading the question I was thinking this question has to be about a done-ish project to be anything comparable? Not someone still working excitedly on getting something working and solving the core problem?
I think many (most?) people would use all their available time to get something going and useful, and then settle into maintenance mode – maintaining compatibility with dependencies, handling incoming issues and PRs, etc – unless something specific kicks them into feature mode again for some time.
@pinskia
@notclacke @pinskia the question is "maintain"!
