SPR flexibilityFlexibility is diminishing. Recall that there are congressionally mandated (read: Legal Acts) sales slated against the SPR to pay for various stuff.
This doc gives a concise breakdown by Act: https://sgp.fas.org/crs/misc/R45577.pdf

So if we were going to be at 410 million barrels in 2028, and we subtract the 180 used to buy votes this year, it brings flexibility down to 230 as the true 'remaining' reserve.
Even if there are no more inflation fighting / vote buying releases, the Administration does have the responsibility to release another 33.5 in 2023, which could be spun in the news. Uncertain whether the 15.5 for 2022 has already gone out, but I would imagine so.
