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 257.45578083352854 > 250.07199194800694.
IsChangePoint: Marked as a change because one of 3/15/2022 12:53:39 AM, 3/17/2022 12:08:34 AM falls between 3/8/2022 5:51:58 AM and 3/17/2022 12:08:34 AM.
IsRegressionStdDev: Marked as regression because -11.78109322334737 (T) = (0 -258.6891193534734) / Math.Sqrt((8.595811911146967 / (36)) + (13.040673937399216 / (6))) is less than -2.0210753903043583 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (36) + (6) - 2, .025) and -0.07611578445829842 = (240.391529507853 - 258.6891193534734) / 240.391529507853 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.
