Yes it takes awhile for things to settle and dialectric to reform. The tuning ring might also work on your other cables. Depending on construction of the other weak link cables you might also be able to shield them with foil wraps of Al followed by a layer of copper foil as RF drain to ground plug. Then also a tuning ring or only tuning ring if you dislike foil look. I have posts in this thread on how to tweak power cables that are lesser to hep increase performance dramatically.
