What happens to your cable between quality checks?

That's the problem the CMVS C29 Express was designed to address.

On a continuous production line, outside diameter, convolution pitch and other dimensional characteristics can change while the line is running. A periodic quality check can tell you whether the product is in spec at that moment. It can't tell you everything that happened since the last measurement.

The C29 Express gives manufacturers of armored and convoluted cable continuous visibility into dimensional variation while the product is actually being made.
