Please critique my home front-end alignment method

If you’re going to do your own alignments it’s best to get a few tools to make sure you can measure and get accurate results. Your method “sounds” good but only if your measurements are accurate. I bought a longacre gauge and made some turning plates and haven’t paid for an alignment since on any vehicle i own.
