Distributions in the correlation observables $\mathit{\Delta }$S (top) and ${\mathit{\Delta }}^{\mathrm{rel}}{p}_{\mathrm{T}}$ (bottom) measured in four-jet production at $\sqrt{s}=7\text{TeV}$ [37], compared to predictions of pythia8 using CDPSTP$8$S$2$-$4$j and of MadGraph (MG) interfaced to pythia8 using CDPSTP$8$S$2$-$4$j (left) and pythia8 using CUETP$8$M$1$ and herwig++ with CUETHppS$1$ (right). Also shown are the ratios of the predictions to the data. Predictions for CUETP$8$M$1$ (right) are shown with an error band corresponding to the total uncertainty obtained from the eigentunes (Appendix A). The green bands around unity represent the total experimental uncertainty
