Here is my view, see if it suit you.
As you said,and,
I already stated it wasn't the 4 section Siu Lien Tao, but the siu lin tao taught to beginners.
it is a fact according to the kuen kuit that the 4 section SLT is not for beginner, beginner doesnt handle the type of details in power generation or energy or movement : such as sink Qi, and flow with medirians... force vectors....short inch jin...etc.
Is this answer your questions?
If you like to know more,
perhaps it is better to ask the person who evolve or create this set to explain his motivation behind it, what he expects one could learn from this set, and what is the different between this set compare with the 4 section SLT.
BTW:
Would you kindly share your name, your lineage, how long you have train, and who is your sifu? So we know who you are and your level depth needed in this discussion.
