TY Dennis, in fact in first L-earning Taut Line for life support were first taught 2up/2down; RT at each tier in synthetics. In time one may advance to as ABoK pictures.
Sorry, not been around and focusing on 1 theory thread when am.
.
i like this as a low utility grade knot, of clean, simple RT, ‘interrupted’ showing the power and flexibility of the mighty RT; that permeates a bunch of knottings.
i have been working with similar , perhaps not as sure footed actually set/family of knots. Will have to draw; but essentially would be like shown only interrupt 1 Turn of RT; either one, and that is the ‘innie’ version(s). Dupe extrovert to outside eye, interrupting either Turn of RT makes total of 4. Extrovert ‘outie’ form of double RT with closest 2 interrupted would be Prohaska/Blake’s form, as we come back full circle.
.
i think of 1Turn(arc180) as a 1D pull, 2Turns as a 1D grip, but 3Turns breaks into stability of more 2D grip, more turns just extend the 2D framework. This is on single, simple or self host, would have to have perpendicular(non-simple host) that is rigid(not rope’s own self) host extension to work on 3D knot forces because natively rope does not resist on the cross axis to go 3D. The other reason favor RT, is how simply and quickly builds friction this early in capstan theory/chart.

Adjustable Ezelius shows some promise , TY!
