How to assess worn Rope?

When people inspect a rope by running their hands along it, are they just feeling for irregularities in the core? Anything else that's more specific? I have some older prussik cord, fine condition, I was checking the other day and noticed a regular, systematic waviness that didn't appear to have anything to do with the outer fibers. I'm assuming that it has to do with how the core is weaved, is that wrong? A lot of ropes seem to have this waviness but to varying degrees. Does anybody here have any specific insights?

It's construction in double braids is typically like 12 strand hollow braid, sometimes single carrier sometimes double. It is generally lumpier than a cover. You can feel this lumpiness in AP 10 mm when new.

I have been climbing Sumac as well. I was installing a cambium saver for a double rope system in a 65 ft American Elm using a throw line tied in the eye of this rope. A cambium saver got caught up along the way at the tie in point and after many tries I brought the system down to inspect and found that I had done this. Where the throw line was tied pulled so tight that it has left the site compressed and remain flat on the inner eye loop. Should I have kept using it? I climbed a couple more times and found I couldn't trust it so I cut it and have been tying an anchor and stopper knot. Thanks to all who have posted here!

Do you still have the spliced section? I would cut it open and check it out. I replace my rope bridge and every 6 months or shorten it if possible. Same with my lanyard where the anchor knots become stiff and flat. Maybe overkill but I am here to learn. Good thread
