Just a thought here and it’s a half baked theory.
Since both CAT 3 and CAT 5 utilize different lengths of paired wire within its own sheath. Would it be logical to think that the electrons would have a timing issue or some sort of anomaly? If so would it be measurable? I know if you remove all of the conductors from a CAT 5 cable (say a 12" piece) and then unwind them individually you should have a few conductors that are longer because of the twists. The same with a cat 3 just not as much of a twist.
Again, it’s just a thought
