It makes sense. I wouldn't know, though
As far as your hair breaking when you do the strand test, try gently tugging, not pulling

I would say that shrinkage is one of the indicators of elasticity. Here is a little excerpt about elasticity. HTH
Elasticity
This is one of the most important properties of hair. Because of its elasticity, hair can resist forces that could change its shape, its volume or its length. Its elasticity lets it spring back to its original form without damage.
When healthy hair is wetted and stretched, it can increase in length by up to 30% and still return to its original length when it is dried. Stretching it more than this will tend to damage it, however, leading to permanent lengthening and even breaking.
The elasticity of hair depends on the long keratin fibres in the cortex. Chemical treatments of hair such as perming and bleaching can alter the cortex after repeated damage, and change the hair's elasticity. Hair with poor elasticity will stretch only to a limited extent. It will not curl, it will break easily when it is groomed and it cannot be permed satisfactorily.
Both natural sunlight and artificial ultraviolet light break down chemicals in the hair and damage its elasticity in the same way that bleaching does, though to a much lesser degree.

I don't really think so. People with straight hair don't have shrinkage, yet they can have good elasticity.

Yup, true. I think it's only an indication, though
Different textures have different ways of indicating different things. That made no sense

from what I have learned Yes it is. ...for our hair type anyway.
What Ubavka123 posted and Den1 said is true.
If your hair natural hair shrinks then it means that your protein bonds havent been broken by heat and or chemicals.

Shrinkage is just an indicator that your hair is curly or coily 
The more shrinkage you have, the tighter your curls are.
