It's worth continuing. It's a well-put-together summary article. Yeah, the cupcake analogy is contrived -- but it's as good an analogy as any other to make it clear that the topic of the article is the difference between a theoretical and experimental measurement.

#6>The task before the Muon g-2 Theory Initiative is to solve these dilemmas and update the 2020 data-driven SM prediction. Two new publications are planned. The first will be released in 2025 (to coincide with the new experimental result from Fermilab).

a bit unsatisfying, basically the Muon g-2 Theory Initiative which gave us the 2020 prediction that turned out to be wildly different from FNAL measurement is going to publish an updated version of the prediction after FNAL releases their final result.
it means the Theory Initiative will have a target that will never move to aim for when working out their final SM prediction

Sure, and this breaks some level of independence between this two workstreams -- it seems unlikely that the Theory Initiative will publish a number that diverges further from the experimental side.
But on the other hand, we're going to be in a world where there are two theoretical estimates, one based partially on empirical methods and one based on lattice methods, and these are going to diverge. So the obvious next task for the theory group is to (a) explain why these diverge and (b) explain why the lattice method is the more accurate one. Which likely will lead to more work for the experimentalists to explain why the inputs to the empirical methods didn't generalize.
Plenty to still learn here.

#9Weren't you guys supposed to save these stories for Muonday Mondays? Weekend's too long of a wait?
