What's the specs on VR1 for zinc and phosphorous?

Mobile1 15/50 are here:
https://www.mobil.com/lubricants/-/media/project/wep/mobil/mobil-row-us-1/pdf/mobil-1-engine-oils-product-guide-sheet--may-2022.pdf

Zinc = 1300 PPM
Phosphorous = 1200 PPM

These 2 are nice to have for the 911 valve train.

EDIT:
Found specs for VR1, slightly better on Phosphorous than M1 but not by much
