Report an error
Report an Error
Found a number that looks wrong? I want to know — error reports are the cheapest quality control there is.
How to report
Email ianwelkins@gmail.com with:
- the page address (or the link the calculator produced — it carries your inputs);
- the numbers you entered;
- what the site showed, and what you expected instead.
With those three things I can reproduce the result exactly and check it against the model on the methodology page.
What happens next
Every report is read. If the number is wrong, it is fixed, the fix is re-verified against the published source, and I reply saying what changed — the process set out in the editorial policy. If the number is right but confusing, that is still useful: unclear presentation gets fixed too.
