Unless they declined to take the envelope money.
Looking at the requirements and the stats, Envelope A requires:
1. Worlds podium
2. National Champion plus Top Five at Worlds.
Brown (2023, 2024) and Pulkinen (2022) both finished 5th at Worlds. Had Zhao not skated in 2022, and had Malinin not skated in 2023 and 2024. It is remotely possible that if Brown (2023) or Pulkinen (2022) had gone in as US #1 with all of the politiks behind them, they might have squeaked out the 1-3 points they would have needed to get on the podium in the absence of Zhao and Malinin . In 2024, Brown was not catching Uno: Brown's PCS were just shy of a 9.4 average.
If that didn't matter, and they ended up 4th each time, then Nationals matters. In 2022, US Nationals went Chen, Malinin, Zhao, Brown, Pulkinen. If they all moved up without change, Brown would have been National Champion, and out of Envelope A with a 4th-place finish. In 2023, US Nationals went Malinin, Brown, Torgashev, Naumov, so if Malinin didn't skate, and they all moved up, Brown would be US Champion again. In 2024, US Nationals went Malinin, Brown, Pulkinen, Naumov, so, again without Malinin, Brown would have had his third title in a row. Brown would have been eligibile for Team A Tier 1 instead of Tier 2 envelope money in 2023 and 2024.
Of course, down the tier, skaters on the cusp 11-13 at US Nationals, depending on how many of Chen, Zhao, and Malinin skated in any given year might have moved up a Tier if they didn't otherwise qualify, there would have been different results at different 4C's, etc.
If I understand this correctly, for envelope money, the % each Tier earns from the fixed pool is dependent on the number of skaters who qualify, so the more top skaters qualify at the higher levels, the less cash there is to distribute to all of the qualifiers. It's not like with WTT, where the maximum amount of appearance money is BIG, but fixed based on the number of people who can qualify for it.
Trivia: had Jason Brown not doubled a planned 3S and had landed it cleanly, the additional base value would have likely put him over Hanyu, who underperformed in his quixotic pursuit of the 4A, and Cha, and he would have been FORTH.
ETA: I forgot what I was coming in to post: I don't think USFS should be paying anyone without transparent criteria that are applied to all skaters.
