Change one thing and compare
Write down the expected effect before changing a number. Change only one input, then compare the resulting totals or calculated fields against your independent calculation. Do not treat a number shown on screen as verified merely because it looks plausible.
Keep your practice results separate from your live work. If the result is unexpected, use the troubleshooting guide and the instructions in the ZIP before continuing.
Keep a practice log
First, record your starting inputs in a separate note. Include the units, dates and references that apply. Next, write down the result you expect. This makes the test useful even if you return to it later.
After that, change one value or one piece of text. Compare the old and new results. If several things change at once, repeat the test with a smaller edit. Finally, remove the practice data before you start real work.
