To be honest I got my figures of 30 and 38 by straddling my bike with a tape measure, putting my hands where they would be with various width bars, and seeing what just felt right. Handlebars are already made in a variety of widths, and it appears that the range of available widths is increasing over time. I'm less interested in width than the long each handlebar simply because the evolution of width is toward optimizing that. The evolution of bar reach vs. stem reach isn't toward optimizing that, as I now find out that's because both of the brain cells belonging to the UCI are not on speaking terms with the other one.
