@evan I feel like this one might have been clearer if you chose options that were either "up to" x%, or "at least" x%.
Wouldn't it depend on many factors *about * the project? There are A+ projects out there that are wholly on one person. And there are great projects out there that couldn't possibly be managed by less than a team numbering in the double-digits (like linux itself, or Python) and in those, a "core maintainer" could be much more PM or QA/Validation than coder.
