Same with Glover, he focused more on his wrestling technique. Older fighters finding success is due to their skillset and it doesn't mean the division is weak, they just found a way to make it work in their older age. Look at the fighters in the division, it isn't weak, they just got beat by more skilled fighters regardless of age.

Ball Milling | Material Milling, Jet Milling | AVEKA
Ball milling is a size reduction technique that uses media in a rotating cylindrical chamber to mill materials to a fine powder. As the chamber rotates, the media is lifted up on the rising side and then cascades down from near the top of the chamber. With this motion, the particles in between the media and chamber walls are reduced in size by ...

Ball Mill Loading - Dry Milling - Paul O. Abbe
The starting point for ball mill media and solids charging generally starts as follows: 50% media charge. Assuming 26% void space between spherical balls (non-spherical, irregularly shaped and mixed-size media will increase or decrease the free space) 50% x 26% = 13% free space. Add to this another 10%-15% above the ball charge for total of 23% ...
