Alright, 26673 LY within 0.3% accuracy:

(So "24650BC" for... context.)

0.3% is +/- 80 years. So it’s not 24650BC, it’s 24570-24730BC. And the farther distance you go, the greater the uncertainty.

And when measurements improve or are revised, everything would need to be recalculated. So, for posterity, it would be 24570-24730BC (2023 measurements).

Or, 2023 is simpler.
