Parameters obtained from fits of ramp-force probability density distributions to the Bell-Evans model (Eq. 1)

Loading rate (pN/s)	k₀ (s⁻¹)	d_tr (nm)	F_average (pN)

250 ± 29	9.4 ± 2.4	2.2 ± 0.35	5.6 ± 0.33
930 ± 120	11 ± 1.8	0.64 ± 0.051	16 ± 0.43
1800 ± 230	43 ± 9.6	0.61 ± 0.13	13 ± 0.89

1100 ± 130	12 ± 3.9(8.7 ± 3.7)^∗	0.33 ± 0.083(0.45 ± 0.085)^∗	27 ± 1.6

Errors are obtained from a bootstrap analysis.

^∗

Parameters from fits assuming that the rupture peaks are due to either a single bond or two independent bonds that fail simultaneously (Eq. 5). The fraction of single bonds is A = 0.6 ± 0.1.
