@TrasteTh battlefieldtracker scrapes the data directly from EA, its accurate. They pulled historical data so it goes back to Day 1. It's updated in real time and you can even see your stats change at the end of round.
If theyre indeed referring to Player Level (which is the only stat I know that is in the Sxxx format) then yeah NOONE is S800+ let alone the max S999. Unless these players happen to have private profiles to not appear on the tracker.
The share amount of XP required is insane.
If you look at the top player at 98M XP, thats averaging 20,000XP per game. I know some players who did farm the Portal mode bots for the relatively short time you could before they patched that out, and playing ridiculous hours they still only got to around S010 before it was closed off. Let alone S100 or higher. Theres no way they farmed 200M XP to reach S999
