So far it has worked on the first attempt every time. So it needs only the delay and nothing else. I still need to test with all my SD cards. Though I only have a 64GB Sandisk and a handful of 32GB Samsung. The question is whether or not the delay is dependent on the card type or if it's just the controller that needs to stabilize.
