This reminds me of https://www.getguesstimate.com/ , a probabilistic spreadsheet.

The authors of Guesstimate are now working on https://www.squiggle-language.com/

Someone also turned it into the https://github.com/rethinkpriorities/squigglepy python library

I was looking for this. Seen it (or a similar tool) ages ago.

Want to use it every 3 months or so to pretend that we know what we can squeeze in the roadmap for the quarter.
