We congratulate Waudby-Smith and Ramdas for their interesting paper
\cite{waudbysmith2022estimating} in generating confidence intervals and
time-uniform confidence sequences for mean estimation with bounded
observations. Their methodology utilizes composite nonnegative martingales and
establishes a connection to game-theoretic probability. Our comments will focus
on numerical comparisons with alternative methods.Comment: 3 pages; 2 figure
