Let U and V be two tasks with the distinct home schedulers. Let
:math:`B` be a time point measured by U right before a call to
${../if/set-scheduler:/name} which moves task V to the home scheduler of
U which preempts the caller. Let :math:`E` be a time point measured by
V right after the first context switch after :math:`B`.
While the execution environment is ${.:/environment}, while the measurement
sample is :math:`E - B`, when exactly ${../val/perf:/params/sample-count}
samples are collected, the ${.:/limit-kind} shall be ${.:/limit-condition}.
