What is a risk of performing automated measurements on a sample of channels?

Automated measurements on a sample of channels can lead to potential undetected problems in the channels that are not measured. By focusing only on a subset of channels, there is a risk that issues such as noise, interference, or other performance problems may exist in untested channels without being identified. This can result in an incomplete assessment of the network's overall health and performance.

It’s important to measure all channels to ensure that any variations in quality or reliability are captured, as problems in untested channels can ultimately affect the user experience and the integrity of the entire system. Thus, relying on a sample for automated measurements may overlook critical issues that could lead to service degradation or failures in other parts of the network.
