Expected and observed 95 % CL exclusion limits for the naturalness-inspired set of pMSSM models from the combination t0L, t1L and tb analyses using the signal region yielding the smallest CL${}_s$ value for the signal-plus-background hypothesis. The dashed black line indicates the expected limit, and the yellow band indicates the $\pm 1\mathit{\sigma }$ uncertainties, which include all uncertainties except the theoretical uncertainties in the signal. The red solid line indicates the observed limit, and the red dotted lines indicate the sensitivity to $\pm 1\mathit{\sigma }$ variations of the signal theoretical uncertainties. The dashed and dotted grey lines indicate a constant value of the stop and sbottom masses, while the dashed light-blue line indicates a constant value of the neutralino mass
