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 49.80377123142251 < 66.31272408544652.
IsChangePoint: Marked as a change because one of 11/10/2021 9:20:40 AM, 11/15/2021 10:42:51 PM, 11/30/2021 5:02:34 PM, 12/3/2021 3:02:06 AM, 12/8/2021 1:12:03 PM, 12/13/2021 6:35:57 PM, 1/14/2022 6:20:45 AM, 1/18/2022 5:19:20 AM falls between 1/8/2022 8:22:56 PM and 1/18/2022 5:19:20 AM.
IsImprovementStdDev: Marked as improvement because 42.58435475358938 (T) = (0 -50070.742171587095) / Math.Sqrt((27869461.378505133 / (299)) + (878531.6697266317 / (19))) is greater than 1.9674995188240387 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (19) - 2, .975) and 0.24104043692526822 = (65972.87208390683 - 50070.742171587095) / 65972.87208390683 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
