This proceeding summarises a flavour physics session talk presented at the Conference on High Energy Physics. The talk explored novel methods for precisely determining the decay rates of $\Upsilon(4S)$ into charged and neutral $B$ meson pairs. These include an overview of previous measurements and introduces a new updated average. The presentation further outlined new determinations for $R^{\pm0}$ at Belle II and the LHC. Theoretical assumptions of previous measurements and the experimental challenges affecting the precision of $R^{\pm0}$ were also discussed.
