Looking at what you wrote, and others interpretations here I think all you're ever going to learn doing these drills is how to be a good copy-cat!
Of course, it is expected that in a large public class, basic methods are introduced as a marching exercise to help coordinate the body, but this is all very very basic training and shouldn't need more than 6 months (2-4hrs p/w) to get to a decent standard imho.
Some of the methods you mention are a little more meaningful, and can nurture with time as long as a good foundation is present. For example:
Mook Yan Jong - Lifelong learning tool, not just a set of 108/116 moves
Chi Sau - Very much misunderstood, and only contributes to a fraction of our interactive exercises
Wall Bag - Something that can be drilled very early on, during SLT learning, and at a later stage if you want to develop 'iron hand'.
Tripod Poles - Moi Fa poles are used, so this term you use is strange to me, but the posts I'm talking of are key to understanding weight distribution of stance and stepping patterns
Chi Gerk - Like Chisau, only a tiny fraction of our interactive practises.
Bridging the gap techinques - I refer to these as 'Entry Techniques' and they tend to be personalised by each Sifu. I call them sansau.
Lop Sau - This is a manipulation method, and fme is more related to the controlling hand than the searching bridge. One main technical drill has become very popular, but this practise is vast.
Tan Da - Again, a very simple drill which can be practised in many ways. Interpretations vary massively though, so good luck!
Jut Sau - Just a name of one hand technique! But it has repetitive uses and a multiple of examples. There is not just one jutsau fme.
Again, this is just my opinion but thanks for putting a bit of life back into the dicussion board Yoshi!!
