Note that this appears to be the same CDC methodology that was found to be misleading in this Stat News piece (i.e. same site as this post) from 2021:

https://www.statnews.com/2021/02/25/cdc-one-year-decline-lif...

(it's literally the same publication from the CDC, just a year later)

At that time, the CDC announced a dramatic decline in life expectancy by extrapolating one-year changes in death rates over the entire expected lifetime of someone born in 2020. This makes small differences look huge. But of course, that's not realistic at all -- we had a significant short-term change in certain age groups (mostly elderly).

When you calculate the impact on life expectancy without assuming that every year after 2020 will look just like 2020, the change is only a few days.
