I think it does help Thrud.
Probably a better question to ask is now that you have done the test, would you preshrink your paracord for a bracelet? I'm thinking cold water might be the better option for a size specific item but everything else, I'm not sure that I would bother.
I'm also wondering if the shrink from cold water would naturally elongate with use (much the same way as jeans after a wash).
I'm sorry I did not test the Paracord shrinking with you (Busy in the workshop) but you might like this youtube clip Thurd.
I wanted to test the strength of a full strand, stitch through eye in paracord. It's a long winded clip but there is some good info on knot strength. Actually, there were a few surprises.
I'm not that creative with paracord but I needed to solve a few construction problems so I delved into the topic. I came across some unique ways to use the cord and though it best to share. The next one will be on how to make your own DIY slim fids from brass tube.
Four strand crown knot variations
By changing the initial layout of the two cords and by crowning to the left, to the right, or alternating left and right you can alter the appearance of your knotting. Finish with single/double footrope knot
Locked footrope/diamond knot
The footrope/diamond knot is attractive but can loosen when handled, especially with synthetic slippery cordage. The locking technique shown in the tutorial eliminates this problem
I've made a heap of these, for various things. The weave is called a quick deploy zipper sinnet. It undoes in a nano second Only two ends needed for the weave, so I use one piece for each one. It's easy. And it's Australian army version of paracord - called hoochi cord. It's smaller diameter, but really strong. I've got a roll of it. Great for travelling too - one strand is strong enough for a clothesline. Here's a video tutorial for the weave https://www.youtube.com/watch?v=jMuvFVWUl4E
just weaved another trilobite bracelet, I now wear these two EDC. I am really liking the trilobite weave, thin and looks great. I did weave the new one a little too big but when I get more buckles I will weave a slightly small one.
