Does the more precise measurement resolve or make more puzzling the g-2 (dipole anomaly) announced by Fermilab a few months ago?

Neither. The g-2 measurement is done with a muon, not an electron. Since any anomalies scale with mass squared, and the muon is 200 times heavier than an electron, that experiment is 40000 times more sensitive to new physics than this one. Doubling the electron measurement accuracy reveals nothing new.

Thanks for the succinct and illuminating explanation!
