Estimating discrete curvatures in terms of beta numbers

For an arbitrary Radon measure $μ$ we estimate the integrated discrete curvature of $μ$ in terms of its centred variant of Jones' beta numbers. We farther relate integrals of centred and non-centred beta numbers. As a corollary, employing the recent result of Tolsa [Calc. Var. PDE, 2015], we obtain a partial converse of the theorem of Meurer [arXiv:1510.04523].
