The mean power trajectories across different $\varphi$ when $n=120$ and $r=0.6$. For each $\varphi$ and sampling distribution, we draw sampling times 1000 times and calculate corresponding power. Vertical bars indicate the 95% confidence interval of power estimates calculated form $\bar{x}\pm 1.96s/\sqrt{1000}$ where $\bar{x}$ and $s$ are mean and standard deviation of power estimates respectively. Maximum power drop $\frac{{max}_{\varphi }\left(mean\text{\_}Power\right)-{min}_{\varphi }\left(mean\text{\_}Power\right)}{{max}_{\varphi }\left(mean\text{\_}Power\right)}$) is 3.8%, 4.4%, and 9.9% respectively.
