My take!
The Look Dim Boon Gwun, Sam Dim Boon Gwun, and the Sap Sam Cheung Look Dim Boon Gwun are names, for differant pole methods, typicaly found within the WCK system though differant pole forms and methods can be found in other Kung Fu branchs, with the same names.
Like all things in WCK, the traditional 'naming' of something, contains ideas about "it" and the concepts and principles involved. 6 and half point pole doesnt mean you can ONLY have 6.5 attacks. It means Litteraly 6 and a half concept pole. A "dim" or point, is way byond a "s'trike". A "dim", is a "Yiu Dim" or "important concept".
While the Dim/Points are concepts, each is "exemplified and manefested in one specific kind of use or strike. So all 6.5 points, and the sometimes included full 7th, have 7 basic strikes/uses.
This pattern and layering of knowledge is found in the entire WCK system. Ok Tan Sau. Look at SLT. We know WCK is a princiiple and concept driven art. We have a Concept of Tan, and a Ging that goes along with it. Really it can be applied anyway ones imagination can, as long as you remain in the WCK context thats outlined in the Principles. But in the SLT form, the Tan Sau concept, is expressed and manefested in the most basic and logical us for said concept.Which is also a litteral technique or strike(with the half point)
So I think the 6.5 points are concepts first and foremost, but each can be applied litteraly as strikes, as found within the forms.
There is so much variation in WCK on everything, we cant even agree on the Half Point. And the "water dripping' pole you mentioned, in YKS Pole, is one of our regular points.
The Half point, is a CORE concept that is applied in every aspect of ones WCK, and has nothing to do with "Lan Gwun" or Sart Gwun typicaly seen in many H.K pole forms IMO.
