Let U and V be two tasks with distinct home schedulers. Let :math:`B`
be a time point measured by U right before a call to ${../if/wait:/name}
which automaticall releases the barrier. Let :math:`E` be a time point
measured by V right after a call to ${../if/wait:/name} returns
successfully due to the ${../if/wait:/name} call associated with :math:`B`.
While the execution environment is ${.:/environment}, while the barrier is an
automatic release barrier, 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}.
