Yeah, but again you might be being too literal. You could get a half dozen "big PRs" out in a month or so, but you'd still want to be able to just focus on "getting your (current) big PR out", you know?

The important part is that you're not interrupted during your large-scale tasks, not the absolute length of those tasks.

That's fair: even if their team has a problem with PR size, this doesn't have all that much to do with the pattern the article describes.
