The four twisted cable pairs in a standard Cat 5 cable each has a different twist rate. So they are of slightly different lengths. The more twists per inch, the longer the actual conductor.

Well maybe, but CAT5 wasn't even invented yet when those standards were developed. I believe CAT3 was the latest and greatest of the day. I believe there was a CAT1 and 2 but those predated the 568 standards.
