Description of detection logic

IsImprovementBase: Marked as improvement because the compare was 5% less than the baseline, and the value was not too small.
IsImprovementCheck: Marked as improvement because the three check build points were 0.05 less than the baseline.
IsRegressionBase: Marked as not a regression because the compare was not 5% greater than the baseline, or the value was too small.
IsImprovementBase: Marked as improvement because the compare was 5% less than the baseline, and the value was not too small.
IsImprovementCheck: Marked as improvement because the three check build points were 0.05 less than the baseline.
IsImprovementWindowed:Marked as improvement because 289.94291181998113 < 297.4455139431709.
IsChangePoint: Marked as a change because one of 1/28/2022 6:30:08 PM, 2/1/2022 5:51:01 AM falls between 1/23/2022 2:39:24 PM and 2/1/2022 5:51:01 AM.
IsImprovementStdDev: Marked as improvement because 62.16779094497242 (T) = (0 -287.3883269377092) / Math.Sqrt((15.64284379481837 / (299)) + (1.5510000243659903 / (17))) is greater than 1.9675476980854363 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (17) - 2, .975) and 0.07575137220509934 = (310.94266011881314 - 287.3883269377092) / 310.94266011881314 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
