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.

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.
