The rules behind every field guide, field note, calculator and chart we publish. Short version: numbers have names, models have labels and dates mean something.
Every number we publish is tied to a named source, and linked wherever a public link exists. When a figure comes from research rather than our own client work, we say so right next to it.
We don't repeat industry numbers that nobody can trace back to an original source, even when they're popular.
Calculators, charts and scorecards on this site are illustrative unless the page says otherwise. They show how a relationship works, like how fill rate drives profit, not a client's data or a promised result.
Example portfolios, sample clients and sample numbers are always marked as examples.
A visible "updated" date appears only after a real change: new sources, revised numbers or a changed recommendation. We don't refresh dates to look current, and we don't quietly rewrite an argument after it's published.
