For hover interactions, the timing guidelines for speed of visual feedback and exposing hidden elements must be broken down into more steps:

Mouse cursor enters the target area: display visual feedback within 0.1 seconds.

Keep displaying the exposed content element until the cursor has left the triggering target area or the exposed content for longer than 0.5 seconds.
