Takeaway
- The relative standard uncertainty fell by a factor of about 11 from the 1986 to the 2022 edition (2.8×10⁻⁸ → 2.6×10⁻⁹): the error bars narrowed that much.
- All 7 earlier editions with a measured value contain the 2022 value within ±1σ (the error bar).
- The largest move between editions came in 2014→2018, at 0.5 times the combined standard uncertainty of the two editions (|z| = 0.5).
- Unit
- none (dimensionless)
- Note
- Sensitivity candidate.
- M1
- Half-life (years): 10.55 (8.30–14.47)
