20/4 is the established regime to do autos. It's not mandatory but many breeders will use it so it stands to reason it's accustomed to that. Higher DLI or less PPFD for same DLI also has some PRO arguments.
Been doing 24/0 alot for seedlings until all are popped to guarantee they always see the light right away. And for revegging. Some early flowering mothers also need that.
