That table should allow me to identify the individual game scores. The games from later stages are more important than those from earlier stages.
The first important stage, 'Qualifying Stage 3: Knockout Qualifier Phase [Q3]', consisted of six knockout (KO) events, each with 16 strong players. Let's look more closely at the first KO event [KO1], which was reported in Nepomniachtchi Qualifies For FIDE World Fischer Random Chess Championship (chess.com; 13 August 2019).
Each of the 15 KO1 matches had at least two games (some had more). Three of those games were embedded in the Chess.com news article. Embedded games have an 'analysis' icon (lower left) that opens an analysis window, which in turn has a 'share' icon (lower right) that displays the PGN, permitting its download. That's fine for embedded games, but what about the other games?
Each player on Chess.com has a profile page. For example, the winner of 'Q3-KO1' has a page titled
GM Ian Nepomniachtchi (lachesisQ) - Chess Profile
(chess.com). The profile pages lead to a page 'Chess Opening Explorer & Database', initialized for that player.
Unfortunately, a help page
How do I use the Game Explorer?
Currently, the Explorer does not index Live Chess games shorter than 5|0, Chess960 games, or any games of fewer than four moves in length.
Fortunately, the site offers an API which is documented in Published-Data API (chess.com). For GM Nepomniachtchi, all of his Chess.com games are available via lachesisq/games/archives. One of the entries there is lachesisq/games/2019/08, i.e. the month when 'Q3-KO1' was played. The FWFRCC chess960 games are mixed in with other games that Nepomniachtchi played that month, but these could be separated.
We seem to have all the pieces to build a database of 2019 FWFRCC PGN game scores. It would be a non-trivial job to gather all of the games, but it should be possible.
Later: Strike everything that's misleading! Re '"Chess Opening Explorer & Database" initialized for that player', I overlooked a checked option under 'Live Games' named 'All Live Types'. Uncheck that and check 'Live Chess 960' instead. For GM Nepo's games in 'Q3-KO1', the result is lachesisQ's Games (8).
It would still be a non-trivial job to gather all of the games, but nevertheless a lot easier than my original suggestion. There's no need to get into the weeds for '[player]/games/archives'. The Chess.com interface works great.
