It's very likely to be some sort of friction apparatus. Nevertheless, the conclusions I summarized are interesting. However, I'm still not 100% sure that lower wear index means less wear. There is a chance that I am looking at the results upside down. Lol.
I don't think I presented much opinion other than summarizing the results.
