all performed with issuing power (fajin): without concentric contraction and only eccentric contraction taking place in the movements/ postures.
If it's real, then the least you can do is show me how you do it. And a description of what differes to the 'regular way' of performance would be a help.
Can you also explain why you think when a tai chi practitioner was scientifically measured why concentric contraction was detected (which I think is fair to assume would be typical) - and then please explain why exactly it would not be detected in your performance. Let's say for argument sake it's a typical Yang style kind of form. Can we do that ?
You must have some answers for that kind of enquiry, otherwise, for me at least, this goes nowhere productive. It would be nice to see it - but a reasonable explanation would make a nice start.
Interesting that you did not mention "grasp the peacock's tail", I think most people work out the application of this signature form of Taijiquan should workout some of your questions.
I have sort of worked on some of your questions in my experiment with fajin workshop:

Experiment with Fa Jin, East Midlands, August 2018
From the classical literature of Taijiquan, Fa Jin has the following characteristics:
1, Store and then issue
2. Store power is like opening a bow
3. Issue power is like shooting an arrow
4. The requirement is the coordination of above and below
Fa Jin is a combination of stored power and generated power to issue an explosive type of power with the coordination of movements of the upper body and the lower limbs. Traditionally the body is described as the movements of 15 joints of arms, legs, and the spine in generating a straight line of attack.
The experiment with Fa Jin sessions will work through various techniques from martial arts that does not use brute force every Saturday from 10 am to 1 pm in August 2018 at the upper hall of Trinity Methodist Church Centre, Royland Road, Loughborough, Leicestershire, LE11 2EH.
Participants will be shown the following:
1. Eccentric strength
2. Stored elastic energy
3, Utilization of stored elastic energy with eccentric strength
4. Utilization of incoming force with stored elastic energy and eccentric strength
5. Practice Fa Jin in various techniques that known to them
The aim of these sessions is to experiment with various possibilities of Fa Jin in martial arts to verify the non-concentric exercise model, and to identify observable differences between pure eccentric strength and combining with stored elastic energy.
