You don't need high amounts of B or Zn.I prefer a decent amount of both. I also prefer a higher amount of ZDDP. Just a personal preference.
Take a look at Boron doped Zinc tryglycerides for example.

Robust Interfacial Tribofilms by Borate- and Polymer-Coated ZnO Nanoparticles Leading to Improved Wear Protection under a Boundary Lubrication Regime - PubMed
This work reports on the development of borate- and methacrylate-polymer-coated zinc oxide nanoparticles (ZnOBM) via a plasma polymerization technique to replace the harmful conventional antiwear additive zinc dialkyl dithiophosphate (ZDDP) in automotive lubricants. Here, the tribochemistry...

But its more expensive to produce compared to normal Zddp.
UOA are supposed to be used with reference the VOA, not to compare add-packs of different oil.
