@jarviloo "Downgrader 2.0" KUAL extension (where all those value were originally listed) was created and last updated at a time when Scribe didn't exist, so it is totally expected for it not to cover doing that edit for Scribe...
Anyways, those numbers were taken from here (usually value form the first /the oldest firmware build was used by Downgrader extension):

So if you scroll that page you'll see this:
Code:
Kindle Scribe
