- The ICC (optimum at 1) describes the ability of a metric to discriminate between subjects across measurement sessions. The SRD% (optimum at 0%) describes a range of values for that the assessment cannot distinguish between measurement noise and an actual change in the underlying physiological construct. Bold ICC values represent acceptable test-retest reliability (i.e., above or equal 0.7). Bold SRD% indicate least strong measurement error (SRD% <30.3)
