On: Measurement of the W boson mass reveals 7σ deviation from calculations

Neat i didn't think about that. But that is less improbable then 1 in 12450197393 which is what you might get with normal distribution.

That's just because Chevyshev bounds is a very weak general statement about all distributions.

High Energy Physics sigma is calibrated to match normal distribution quantiles.
