What to write about
- A wrong number. Send the sizes you entered (or the share link) and what you expected. Every formula is meant to match a published source, so a mismatch is a bug.
- A source we should cite. A standard, extension publication or lumber rule that covers something the calculator does, or does differently.
- A feature request. Something you'd use at the yard or in the shop.
GitHub
If you have a GitHub account, you can also open an issue. The code and the formula tests are public there.
