Contact

The way to reach me is email: ianwelkins@gmail.com. There is no contact form on this page on purpose — a form would mean your message passing through a server and a database, and this site is built so that nothing you type goes anywhere. An email link keeps it simple: your message travels from your mail app to my inbox, and nowhere else gets involved. I'm Ian Welkins, the developer behind this site, and every message lands with me personally.

Corrections. If a number, formula or worked example on this site looks wrong, that is the most valuable email I can get. The fastest route is the report-an-error page, which walks you through the details I need — the page, what you entered, what you got and what you expected — but a plain email with the same details works just as well. I check every report against the published source myself, and confirmed errors are fixed and dated.

Feedback. If a tool confused you, a table is missing the distance you race, or a page explained something badly, tell me. Most improvements to my sites start as a reader saying a page nearly answered their question but not quite.

Source suggestions. If you know a published source — a governing-body document, a study, an official event guide — that a tool here should be using or should be checked against, send it. The site's standard is that every figure traces back to a named source, and better sources make better tools.

I'm a developer, not a swim coach, so I can't build you a training plan, critique your stroke or tell you what pace you should be aiming at — a coach who has watched you swim will always give you a better answer than I can by email. I also can't give medical advice of any kind, including about training through pain or injury; that belongs to a medical professional. And while I'm glad to fix this site's numbers, I can't verify or correct times from other websites or apps — each tool's figures stand or fall on its own sources.

This is a small, one-person site, and I fit the inbox around building and maintaining the fleet. I read everything, but replies can take a few days — longer when a correction needs checking against a source document before I answer. Error reports get priority, because a wrong number affects everyone who uses the page after you. If your message is about privacy or your data, the privacy policy explains what the site does and does not collect, and the same email address reaches me for questions about it.
