Those vendor-specific coefficients are where the most of the magic are hidden. Possibly, there are some differences too between your configuration and mine. Possibly hardware differences.
BTW on a back of my notebook the model is listed as UX534F, QR code on the back redirects to the page for UX534FT, dmidecode shows "Product Name: ZenBook UX534FTC_UX534FT" in the "System Information" and it was sold to me as UX534FTC-A8101T. Which is a complete mess, thanks to ASUS.
