| The 176Lu+ comparison became statistically limited after approximately 200 hours of averaging, with measurement instability of 4.8×10⁻¹⁶(τ/s)⁻¹ᐟ². | QUANTITATIVE | Supported | 0.8808 | 1 of 4 | 145 |
| Direct correlation spectroscopy reported a relative frequency agreement of −2.4×10⁻¹⁹ with ±5.7×10⁻¹⁹ statistical and ±1.0×10⁻¹⁹ systematic uncertainties. | QUANTITATIVE | Supported | 0.8808 | 1 of 4 | 145 |
| Two independent 176Lu+ single-ion optical references were reported with total systematic uncertainties of 1.1×10⁻¹⁹ and 1.4×10⁻¹⁹, and 9.6×10⁻²⁰ for their difference. | QUANTITATIVE | Supported | 0.8808 | 1 of 4 | 145 |
