As "other" says above, that variation in twist from one pair to another is called "skew".
CAT-6 has a different rate than CAT-5E (Big E)...
which is different than CAT-5e (little e)...
which is different than CAT-5 (no E)...
which is different than CAT-3!!
Skew is NEEDED for data runs for the crosstalk reduction reasons outlined in this thread.
Reducing the crosstalk allows for higher usable bandwidth, because less of the cable's capacity is cluttered with errant information from the other pair(s) or from outside.
