Found a value that disagrees with the source? Want a cheat sheet that doesn't exist yet? Have feedback on the design? We'd like to hear it.
What to include for a correction
- The page (URL or cheat sheet name)
- The specific value you think is wrong
- What you think the correct value is, ideally with a source citation
We take corrections seriously — please include the source, not just "I think this is wrong."
What to include for a feature request
- What cheat sheet or calculator you'd want
- What you'd use it for (helps us prioritize)
- What the closest existing tool is, if any
Response time
This is a side project. Corrections we usually act on within a few days. Feature requests we batch and review monthly. Either way, we read everything.
