Stylus Rake Angle should be the first parameter determined in the optimal analog setup. As a result, impacts to azimuth by changes to SRA are accounted for when determining ideal azimuth.

 

It is important to understand that if you raise/lower your tonearm from the level position in order to accommodate your ideal SRA, unless your tonearm has an offset yoke (see photo for example) your left/right axis is also no longer level. This means that unless you compensate for it, your azimuth measurements will be started with that axis off level in the amount determined by this calculator.
