Abstract: Let $\D=\{z\in\C:|z|<1\}$, and let $\mathcal A$ be the class of analytic functions normalized by $f(0)=0$ and $f'(0)=1$. For an admissible Ma--Minda generator $φ$, write $\Sstarφ=\{f\in\mathcal A:zf'(z)/f(z)\precφ(z)\}$. Given two generators $φ_1$ and $φ_2$, we study the largest $R\in(0,1]$ for which $f(rz)/r\in\Sstar{φ_2}$ whenever $f\in\Sstar{φ_1}$ and $0
