CCDFs of stress drops in the most slowly-compressed sample (5 × 10−5 s−1) of Zr64.13Cu15.75Ni10.12Al10 at various average applied stresses.
Stress drops above the threshold of instrument-noise fluctuations (10 MPa) only set in around 92.0% of the maximum applied stress. Thus, small windows of stresses were examined: 94.0–96.0% (green dotted line), 96.0–97.0% (purple dashed line) and 97.0–97.6% (black solid line), with the weighted average stress values given in the figure legend. The stress-binned stress-drop PDFs are hypothesized to scale as a power-law dependence of S−κ multiplied by a scaling function dependent on S(1 − τ/τC)1/σ, see Equation (3) in the main text, which expresses the distance from criticality19. Because the bins of stresses are small, τ is taken to be the average applied stress within each bin. The resulting scaling collapse (inset) was quantitatively verified for the exponent values of κ = 1.4 ± 0.28, 1/σ = 1.85 ± 0.20 and τC/τMax = 1.05 ± 0.01. With these values and the collapse function, 
, shown in the inset, we can predict the slip statistics at other stresses, see Equation (4).
