Hi K4u,
When I started to attempt to categorise knots based on their component parts, I had in mind my chemistry background, and naively thought that a knot could be described much like a molecule - by defining its component atoms and describing how they were arranged. But over time I realised my error. In chemistry, a Sodium atom is always a Sodium atom with exquisitely fixed properties, but in a knot, any component can morph and slew through an infinite continuum of forms - from an identifiable hitch, through a hitch / turn hybrid, through to a turn, and exhibit all those properties in turn and in part simultaneously by degrees.
Sadly, the more I study knots, the more I believe we are further than ever from a Science or Physics of knots - certainly, I do not possess a mind capable of taking us there. But I do not give up hope that the scratchings and searching for understanding that we do today, will offer some chance in the future for some bright mind to make a breakthrough. To that end all our confusion and mumblings may have some value.
On the particular issue at hand, there is little chance of moving forward, because the arguments proposed are simply opinions, and every one is valid although each might be at odds with the other.
Mark asked - “What defines a Bowline?” - I have answered that with my opinion, but that is all it is - a single persons opinion, my definition. Someone else defines a Bowline differently and there you have an equally valid opinion and definition.
Unfortunately, the question has a very familiar counterpart - ‘How long is a piece of string?’
