Wow, I would have definitely assumed it would not matter in the end as you'd either have to pay it back/get a refund depending on what is the official year they end up going by, but guess everything I'm reading is saying its possible there may be no official year to go by? Nice catch.
I doubt I'm eligible either way, but should be FIRE soon after so will be eligible for the 2022, 2023, and 2024 checks.
