black_scholes is the only kernel in the suite that runs under 1 ms, and its
confidence interval on aarch64 is wide enough that the number carries no
information — see docs/bench-aarch64.png, where its whiskers dwarf every other
kernel's.
It also explains a discrepancy with older reports: those took the min across
rounds, which picked the floor of the noise and made the kernel look stable.
Needs more reps or a larger workload before any aarch64 black_scholes
comparison is worth quoting.
