Description of detection logic
IsRegressionChecked: Marked as regression because the three check build points were 0.05 greater than the baseline.
IsImprovementBase: Marked as not an improvement because the compare was not 5% less than the baseline, or the value was too small.
IsRegressionBase: Marked as regression because the compare was 5% greater than the baseline, and the value was not too small.
IsRegressionChecked: Marked as regression because the three check build points were 0.05 greater than the baseline.
IsRegressionWindowed: Marked as regression because 75.93536301666667 > 70.84351980125.
IsChangePoint: Marked as a change because one of 6/22/2022 5:33:38 PM, 8/6/2022 1:07:13 AM, 8/11/2022 10:02:44 AM falls between 8/2/2022 9:32:02 PM and 8/11/2022 10:02:44 AM.
IsRegressionStdDev: Marked as regression because -24.83915370249787 (T) = (0 -76684335.4223952) / Math.Sqrt((1825236129188.6467 / (23)) + (2631504391413.2695 / (27))) is less than -2.010634757623041 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (23) + (27) - 2, .025) and -0.15768388595046612 = (66239442.695046976 - 76684335.4223952) / 66239442.695046976 is less than -0.05.
IsImprovementBase: Marked as not an improvement because the compare was not 5% less than the baseline, or the value was too small.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
