Jason,
Thanks for this thoughtful analysis. I think you've done an excellent job laying out your reasoning.
Unfortunately, as you know well, any analysis of the gender gap and the retention of women editors necessarily involves a lot of estimates and extrapolations.
Some of that is unavoidable without conducting a new full-scale research project (such as getting an accurate, up-to-date % of women editors to replace old estimates from previous studies). But other estimates can probably be replaced with fresh data at reasonable cost, and could refine your projections.
For example, it shouldn't be too difficult to generate new editor retention numbers, like those from the editor trends study, with publicly available data. It's possible that we're retaining active editors at a different rate than we were in 2009. We're certainly retaining new editors at a lower rate than we were back then.
Thanks again for sharing! Please keep us posted,
Jonathan
