Table 7:

Comparing the average sample sizes at decision for each sampling scheme when evaluating the type I and type II errors control.

Sampling scheme	Type I error (Q = Q₀) Average sample size	Type II error (Q = Q1) Average sample size
i.i.d (Q, g^b)-balanced	786.63	895.64
i.i.d (Q, g^★(Q))-optimal	620.71	713.47
adaptive $(Q, g_{n}^{★})$	661.14	746.72
