r/codex is reporting that $20 (Plus) seems to have had its usage limit reduced (some people are saying it feels like 1/3 the previous limit now). The theory[1] is that reducing $20's limit lets them claim $200 has 20x $20's limit (and $100 has 10x).

If that's true, then the value comparison is not so positive for Codex any more
