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 we could not find enough baseline builds for window checking.
IsChangePoint: Marked as a change because one of 11/8/2021 9:55:37 PM, 1/6/2022 4:51:33 PM, 1/11/2022 6:41:22 PM falls between 1/3/2022 4:56:39 AM and 1/11/2022 6:41:22 PM.
IsImprovementStdDev: Marked as improvement because 32.69853313161565 (T) = (0 -3333.8411996858695) / Math.Sqrt((50908.90855909807 / (299)) + (206.12402908028994 / (4))) is greater than 1.9678765312856872 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (4) - 2, .975) and 0.12745246775295188 = (3820.81328119778 - 3333.8411996858695) / 3820.81328119778 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
