Opening and Closing by Watchtower to boost ritual work

Has anyone strictly and devotionally worked with Watchtower ceremony in ritual opening and closing? I’m assuming that it may work with Enochian Watchtower tablets.
I wonder because in Ceremonial Magic by Regardies, he includes different versions. King and Skinner in Techniches of High Magick utilized it. Crowley utilized it. LaVey I think did.
Point being is it works, yet most don’t speak on it.
