Wildberger kind of notoriously is a non-believer in real numbers, which sort of comes across with the statements about it being the only "completely accurate" trig table and comments about how the base 60 system is somehow richer and more accurate than decimal numbers.
Seems to me, an ignorant on the subject as a whole, that they came up with a quite complex explanation that fits the data, but we can’t know for sure and most likely never will. And this is a problem with mathematics because it is self-consistent: we can build a whole theory on top of the contents of the tablet and it will produce the correct results. We just can’t know if what we came up with was the same thing they used back then, or if we are just doing modern mathematics with some old data.
Heres a video on what they're talking about: <a href="https://www.youtube.com/watch?v=L24GzTaOll0">https://www.youtube.com/watch?v=L24GzTaOll0</a>
