The elbow behaviour - one of VT's most common and consistent elements (even between all the different lineages we have) is taught and made habbit by way of Chi Dan Sao and forms, in the very early stages of ones overall training.
As a result you'll see the same behaviour of my elbow displayed in Chi Sao as being the same as when i fight, bar the dynamics of a totally moving environment
. This doesnt mean i dont have things from outside the box also....
You would also find the energy use in the main parts of my vt engine (the shoulder the elbow the wrist and the waist) would show more similarities between fighting and the chi sao drills i do, than differences.
So for me there are direct applications of Chi Sao and forms to my fighting
Behavior. The drills are just to concentrate and isolate certain elements and wont do me harm if i realise their position/relevance in the training food chain.
I agree though there are other ways to train these elements as you see fit and other aspects of training are needed to support them.
But one cannot say IMHO that there is
no correlation to fighting unless you have only touched the surface or are looking for shapes.
Our minds are what makes or breaks this approach.
