Notes
-----

 - μ_1k,μ_100,μ_20,μ_4: weighted mean values of the last 1000 / 100 / 20 / 4 computed averages
 - σ: estimate of the "asymptotic standard error" of the weighted mean value as computed by gnuplot. Note that, (a) gnuplot tends to compute an overly optimistic estimate, (b) the weighted mean value and asymptotic standard error do not factor in systematic effects present in performance tests. We nevertheless use this value as a baseline but with rather large thresholds for the triggers.
 - r𝛘²: reduced chi-square value of the weighted mean value. A value much larger than 1 indicates "underfitting", a value much smaller than 1 indicates "overfitting". The status of the measurement is reported in the "stability" column based on the reduced chi-square value of the A20 average.
 - Δ: The μ_20 and μ_4 weighted mean values are compared to μ_100, and the μ_100 mean value is compared to 1000.
 - When normalizing the deviations Δ with σ, a noise floor of σ_sys = 5ms is added.
 - Status: status triggers are set at a deviation between μ_20 and μ_100 of 3σ asymptotic standard error for a "consensus regression", or "improvement" and 4σ for a "minority regression". The "deviation" trigger compares μ_4 with μ_100 with a threshold of 3σ.
