We consider finite charm quark mass effects both in the QCD potential and the $\\overline{\\mathrm{MS}}$-pole mass relation up to third order in the $\\Upsilon$-scheme counting. The $u = 1/2$ renormalon of the static potential is canceled by expressing the bottom quark pole mass in terms of the MSR mass. A careful investigation of scale variation reveals that, while $n = 1, 2$ states are well behaved within perturbation theory, $n = 3$ bound states are no longer reliable.
