Jump 1/4 to 1/4 turn…? Jump 1/2?
Honestly, no one has had need to call this anything
This is a weird one because it’s such an unusual mount. It certainly falls into the category of “complicated nonsense,” where one person did a thing, and it was kind of a different way to mount the beam, and now it’s in the code of points, and just sitting there because no one else would have any reason ever to do it.
That in itself is a common phenomenon in the behemoth beam mount section, but i say it’s weird because this is the kind of mount you expect to be named after someone. The person who did this weird thing and said, “I have a mount now!” But it isn’t. It’s just sort of there.
