It wasn't the measurements that were the problem, it was the calculation of what the standard model predicts.

Right. I mean that measurements conflicted with theory, and the new CMD-3 measurements suggest a better calculation. Assuming CMD-3 is good, there's no significant gap between theory results and collider results

[pfdietz]

That wasn't the only change. There was an alternate computational scheme that didn't depend on electron-positron experiments that gave results consistent with the Muon g-2 experiment.

Fair enough, I suppose! Thanks for the the correction.
