Wow, all that to tell me you have no definition of "quality of ride" or even where you stand on a "jnd". No, not exactly, I shaved metal off, spun the hub, rim & spokes repeatedly to get an average of test results and went back to work to balance it better. Gee, sounds like a similar process to wheel truing doesn't it. Not noticeable by a human being, I wonder if a human being used a higher quality grade of lubrication like a synthetic grease whether a human being would notice a difference. What is that, viscosity/film strength and a reduction in friction. Just curious how that effects "quality of ride". Where would you stand on that as an assertion of improving the "quality of ride".
