I see. But that's still only the first, "plannable" part. If the research (or algo design) led to the conclusion that component X needed a rewrite, would it require waiting half a month to get started? Maybe that makes sense if it's a larger thing (so that detailed planning would be worthwhile), but would you be required to drop it and do something else in the meantime even for smaller ones (say, a man-day of work)?
