The passage around this formula

Minimizing over T gives an optimal interval $T^{*}$ = $\sqrt{2\tau/\lambda}$ : the checkpoint interval should shrink as the inverse square root of the fleet failure rate, not linearly with it, so frequency rises roughly as $\sqrt{N}$ purely from the failure-rate side as accelerator count N grows. Comparing that to MLPerf’s own reported tightening…
