Tool assumptions & limitations

Last updated November 11, 2026

Check the assumptions

You write and check your own cards. Review intervals are organizational choices, not a guarantee of learning outcomes.

Inputs determine the result

Example values illustrate how a tool works. Replace them with your measurements and requirements. Rounding, allowances and supported cases are explained beside each tool.

Limits

These tools do not perform bookings, purchases, inspections or professional assessments. Guides are general reference material. Consult the relevant provider, product instructions or a qualified professional when your situation requires it.
