The Shadowstats numbers are deeply suspicious though; the graph makes it look like Williams is just adding [0] a constant to the BLS figure, which undermines his credibility. I'm also pretty sure he changes his constant every so often because I remember at one point his data implied absurd drops in the GDP and it appears the website has been changed since then.

I'd suggest just referring to the M2 [1]. It is easier to understand, and more available for analysis. Apparently it also gets rid of the stupid "real" price rises that inflation pretends gold is experiencing [2]. It suggests prices should be about 40% higher than pre-pandemic (I checked 2019-11 -> 2023-12) which coincidentally lines up with what justinzollars is reporting.

[0] Well, smoothing in. But the two lines wiggle the same way which suggests we're just using the BLS + an adjustment that is changing in a boring way over time.
