Are you saying the length of the cable from one end of the sheath to the other is 14.1 feet ?
If so the 16 feet measurement could well be correct as the cable is twisted therefore longer. also each pair has a different twist ratio therefore each pair will yeild a different results.
Take two peices of single wire each 10 feet long, tie one end to a chair, put the other in the chuck of a cordless drill and twist it up. then see how long the resultant twisted pair is, it certainly wont be 10 feet.
