Are those numbers better than say QSUD at nearly 1/3 the cost?
UOA's aren't designed for that purpose, you can't just compare wear metals and divine performance, that's not how it works. You'd have to do tear-down testing to truly gauge any sort of performance difference and I doubt anybody is interested in doing that.
