The major concern is that you want to ensure the Sequence is flowing smoothly without too much downtime, numbers may differ or may be higher, I have seen people get higher numbers. Usually I try to sim my character on raidbots and try to aim for 80% of that sim and the second thing I aim for is making sure the sequence does not have much downtime.
i havnt played wow since legion, i have no idea how to do any of that
