There is a little bit of "play" in the DSS shaft when you factor in the front and rear yokes. There is a dimension near the CV joint that cannot be exceeded once installed. I forget the number, but mine was really, really close to being over.
What is the purpose measuring the length of the drive shaft? It not like there is anything to adjust here.
