I read everything and respond within 48 hours. If you're reporting a calculator bug, include which calculator and what inputs you used — helps me reproduce it fast.
What I Want to Hear About
- Calculator requests — What calculation do you need that doesn't exist here yet?
- Bug reports — Something calculating wrong? Let me know.
- Formula questions — Want to know how a calculation works? Ask and I'll explain (or add it to the guide).
- General feedback — What works, what doesn't, what's confusing.
Note: Punch The Numbers is a one-person project. I answer every email, but might take a couple days during busy stretches.
