percent divided by fifty percent, so one unit of time. Let’s call it one hour. So, on average, our task would wait in the queue for one hour before it gets worked. On the other hand, if a resource is or nine hours. In other words, our task would wait in queue nine times longer than if the resource were fifty percent idle.” I conclude, “So, for the Phoenix task, assuming we have seven handoffs, and
