  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/release:/name} which unblocks task V which is scheduled on
  another processor.  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 semaphore is
  a priority inheritance mutex, while exactly task V waits on the mutex,
  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}.
