How this is done

Four rules, applied to every project here. They are also the reason a paper takes months rather than an afternoon.

01

Public inputs only

Everything starts from filings and records anyone can obtain without a licence, a subscription or a relationship.

02

Working papers ship with data and code

Not on request — at the same time, in the same place. Research notes link every source series they use and say what is not published.

03

Versions are stated and logged

When a number changes, the page gets a new version and a dated changelog entry; earlier versions of a working paper stay on Zenodo. Silently updated figures are how a record becomes worthless.

04

Nothing here is peer-reviewed

Each page says so on its face. When something turns out to be wrong, the correction goes on the page that was wrong, marked and dated.

Found an error in any of it? Write to mail@profit-owl.com. A correction that arrives is worth more than a paper nobody checked, and it gets published on the page that was wrong.
