Three-point or PERT estimates are in the same vein, but are just an old and established business process concept and not a trademarked "project" from a (defunct?) consultancy.

And yeah, they can be useful when you can must put numbers to things and can decompose the work into familiar enough tasks that your estimation points are informed and plausible. Unfortunately, in a field often chasing originality/innovation, with tools that turn over far too often, that can be a near-impossible criteria to meet.
