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 545.9992042440318 < 557.2944737611924.
IsChangePoint: Marked as a change because one of 3/14/2022 10:40:48 AM, 3/16/2022 7:30:14 AM, 4/26/2022 10:28:11 AM, 5/5/2022 2:36:12 AM falls between 4/26/2022 10:28:11 AM and 5/5/2022 2:36:12 AM.
IsImprovementStdDev: Marked as improvement because 25.39951958985009 (T) = (0 -546557.2486523489) / Math.Sqrt((1338664360.6179235 / (299)) + (1560558.1376858016 / (31))) is greater than 1.9672228266464409 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (31) - 2, .975) and 0.08998433857814042 = (600602.0245831562 - 546557.2486523489) / 600602.0245831562 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
