In a speculative decoding process, the number of consecutively accepted tokens from the start of a draft sequence, denoted by $n_a$, is determined by finding the index of the first rejected token. The formula is: $n_a = \min \{t-1 | 1 \le t \le \tau, r_t > \frac{p(\hat{y}_{i+t})}{q(\hat{y}_{i+t})} \}$.

Given a draft sequence of 5 tokens ($\tau=5$) with the following randomly generated numbers ($r_t$) and probability ratios ($p/q$), what is the calculated value of $n_a$?

• t=1: $r_1$=0.4, $p/q$
