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 63.2191727660926 < 71.40381419630653.
IsChangePoint: Marked as a change because one of 5/31/2022 10:47:41 AM, 6/6/2022 8:15:49 PM, 7/7/2022 8:07:51 AM, 7/14/2022 8:56:55 AM falls between 7/5/2022 7:51:46 PM and 7/14/2022 8:56:55 AM.
IsImprovementStdDev: Marked as improvement because 17.540714388948963 (T) = (0 -65942.7673409517) / Math.Sqrt((15947001.086585244 / (299)) + (14299697.736768063 / (30))) is greater than 1.9672451058622664 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (30) - 2, .975) and 0.1622325066343994 = (78712.49226445501 - 65942.7673409517) / 78712.49226445501 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
