We try to approach it on an individual basis, so there is no fixed formula for determining a court's judicial complement. That is because the jurisdictions' courts themselves are responsible for the administration of justice. For example, the rules of court and civil matters are not identical across the board. Each request is considered separately on its merits and without comparing one jurisdiction to the other.
That said, we do keep in mind, for example, that in criminal matters we know that the Supreme Court has spoken to what presumptive timelines should apply, so those do help us and guide what should be expected.
