Currently two knobs: samplingConfidenceInterval and samplingMarginOfError are used to control the CE sample size. This is confusing to everyone involved: engineers, testers, support team, and customers.

It also gives a false sense of confidence in the results of sampling CE. For example, the default values: "confidence interval = 95%" and "MoE = 5%" are based on certain statistical assumptions that are not always met in practice.
