We present a comparison of the computation of energy-energy correlations and Durham algorithm jet rates in $e+e−$ collisions at next-to-next-to-leading logarithmic accuracy matched with the $O$ $(α3s)$ perturbative prediction to LEP, PEP, PETRA, SLC, and TRISTAN data. With these predictions we perform extractions of the strong coupling constant taking into account non-perturbative effects modelled with modern Monte Carlo event generators that simulate NLO QCD corrections.
