The calculational precision of $\ee\to\tautau$ and $\ee\to\mumu$ production cross-sections in electron-positron annihilations at \roots = 10.58 \gev are studied for the \kk Monte Carlo simulation program. We determine $\sigma(\ee\to\tautau) = (0.919 \pm 0.003) \nb$ and $\sigma(\ee\to\mumu) = (1.147 \pm 0.005) \nb$, where the error represents the precision of the calculation.

    Belle II sets upper limits between 1.3 and 2.5 times 10 to the minus 8 on branching fractions for four tau to e l l decay modes at 90 percent confidence level, the most stringent to date for four modes.
