Ragnos MAY be though the quotes are ambiguous and can be seen as of his time or ever though he has no "of all time" or "up to his time" quote.
Freedon Nadd is not confirmed to be above Ragnos.
Your scaling is flawed.
Karness Muur was one of Ajunta Pall's Shadow Hands:
"Ajunta Pall beheaded their ruler, Hakagram Graush, and claimed the throne as the blood heir to the ancestral King Adas -- and we became his Shadow Hands."
- Sorzus Syn, Book of Sith: Secrets from the Dark Side
Tulak Hord is stated to be amongst the greatest Dark Lords of the Sith ever, which would include the aforementioned Ajunta Pall, whom as stated previously, was Muur's master and confirmed superior:
Centuries ago, Khem Val was the proud servant of Tulak Hord, one of the greatest Dark Lords of the Sith to ever live.

Marka Ragnos is confirmed to be the greatest Dark Lord of the Sith up until his time:
Meanwhile, on the far side of the galaxy, the Sith Empire has grown powerful through centuries of dark Force wielding and magic and the hundred-year rule of the greatest Dark Lord of the Sith, MARKA RAGNOS.
- Chronicles of the Old Republic
Freedon Nadd is stated to become the greatest Sith sorceror who ever existed:
He only needed time to become the greatest Sith sorcerer that had ever existed . . . .
- Tales of the Jedi Companion
Which obviously includes Marka Ragnos. Whilst it is not a direct statement of superior power, sorcery is considered in-universe to be the greatest source of power. It is fairly cut and dry.
Exar Kun became even more powerful than Nadd, before he was in his prime.
