Maybe it's also work to further develop an understanding of the geometry involved in playing over the whole neck and how the different types of setup mix advantages with compromises. I set up my own guitars how I personally prefer them, but I set up guitars for others in ways that hopefully best suit the specific player and their technique. Since I've spent decades developing an understanding of the various types of setup as related to playing style, I don't need to go through a personal process of discovery like @DugT describes. Rather, I choose a relief that I think will suit the player after watching them play and asking them some questions to ensure that they don't leave any technique out of their demo, and then set the action, with little or no need to tweak the relief further, unless there are fretboard problems they don't want to fix, which require an amended relief theory. By theory I mean my assumption of what would work on a good neck. Many players just want the $40 job, so you gotta work with their budget!
