If software hasn't already added the offset then yes, subtract 20*c.
As much as I don't agree with their way of doing it either I believe their line of thinking was as follows.
XFR needs to start at lower temps, so cool it before XFR might want to kick in and XFR at 100mhz on the X series generates more heat. Benefit those who bought an X by tricking the system into keeping it cooler, sooner to give them more headroom. It's easier to keep a CPU cool than to try and bring it's temp down after it has.... Ryzen. Instead of relying on fan profiles, software or other means, they just baked it into the hardware so that regardless of what software you use, it will be more aggressive with cooling. On top of that, they probably assumed (I'm sure correctly) that most software developer with temp readings can add the Ryzen X SKUs into the software to automatically subtract 20*c. So long as those softwares don't negate AMDs odd method of forcing aggressive fan curves for your XFR's benefit.
I guess it beats the heck out of running a piece of software in Windows (Linux, ect) to try and force a fan profile that would have been provided by AMD themselves. Or like Intel and Optane's reliance on a software.
Really want to find out the benefit of it... Someone needs to find a way for the X chips to report normally and benchmark against it with the factory offset. See what all of the hub bub is about.
