First, doing RR testing is a lot more involved than you might expect. The machinery involved to get consistent, reliable results is expensive and I haven't even mentioned the procedures.
Second, there are many different RR tests and they yield different numerical results. So in order to do comparisons, the tests must be the same.
Third, it has been estimated that if EVERY RR testing machine in the world were to be utilized 24/7/365 to test existing products, it would take 3 years - and during that time, nothing else could take place. No improvement testing, no prototypes, no research.
etc.
So while I admire the idea, I just don't think it it practical.
Now if you want MY solution to the problem, I can give it, but I give far warning: It is long and complex - to the point where TL: DR applies.
