I suggest putting a sentence in about the point of the post / the methodology, e.g.: “This is part I of an attempt to write a detailed plausible future trajectory in chronological order, i.e. incrementally adding years to the story rather than beginning with the end in mind. The hope is to produce a nice complement to the more abstract discussions about timelines and takeoff that usually occur.” If space is a concern then I’d prefer having this rather than the two sentences you wrote, since it doesn’t seem as important to mention that it’s my median or that it’s qualitative.
