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 241.2080003434066 < 242.36396851118468.
IsChangePoint: Marked as a change because one of 11/1/2021 4:11:40 PM, 2/3/2022 8:57:20 PM, 2/8/2022 11:58:21 PM falls between 1/31/2022 9:06:05 AM and 2/8/2022 11:58:21 PM.
IsImprovementStdDev: Marked as improvement because 23.102979836430574 (T) = (0 -240622.53782814337) / Math.Sqrt((27706792.18811416 / (299)) + (9684580.08785857 / (18))) is greater than 1.9675235316906419 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (18) - 2, .975) and 0.07084819383658643 = (258970.1017982245 - 240622.53782814337) / 258970.1017982245 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
