your logic, facts, and understanding of the laws of physics are so sketchy that I don't even know where to begin trying to address the flaws in your arguments

You perceive an improvement in ride quality because you want to believe all your time and effort made some kind of difference. There's no way a few milligrams of weight could make a difference that you can actually notice while riding your bike. Not even if your frame, rims, spokes, hubs, etc. were all perfectly rigid and your tires & tubes perfectly solid and incompressible, and the road as smooth as glass. It's not possible for such a tiny amount of imbalance to cause any sort of wheel "hop".

I did say that all the components, rider, road surface, etc. affect ride quality, but the chances of a human being able to sense a difference in ride quality before and after shaving a weld seam on the rim are "one in a million"
