If the trigger point is set to onElementHover then this value is used to delay or prevent the accidental firing of the box and attempts to determine the user’s intent. It is recommended to use at least 30 ms.

Use Cases

Open box as soon as the page finishes loading

A use case for this trigger would be when you want to show a box once the page has finished loading, including all the assets of your site have finished loading. This essentially means your box will appear a bit delayed than Page Ready but ensures your page is fully loaded.
