You're certainly right about that. The slower it drys the better, because you need enough time for the chlorophyll in the plants to decompose. If you dry your bud too fast, yes it'll be dry, but it'll smell and taste like fresh lawn clippings or hay when you smoke it.
In the end there's more than one way to skin a cat. Just dry the bud slowly over the course of several days, in the dark. You want some light air movement, but you don't want it focused on the bud directly. I personally wouldn't risk hanging it for 24 hours without airflow. IMO that's the prime time for mold to start growing. The air flow will help prevent that at any stage of drying, but especially in the beginning.
