Every product comes with a degree of variations.
Therefore the selection by weight (Boll example) is not a big deal.
Sponge hardness on commercial products also varies, and I am sure if they do a run of a dedicated Ma Long 41,5 hardness even some of that wouldn´t be 100% precise.
But yes, you can measure and hand-select the ones that are and sell the rest as 41 degree National or whatever...
Yes they aren't 100% precise. The commercial one might be 80% precise, national might be 96% and the celebrity-level rubbers are probably 99% precise.
But I can't even tell the slight difference between the provincial and national rubbers 😆
