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 86.96249615384616 < 88.43986308333334.
IsChangePoint: Marked as a change because one of 12/9/2021 12:47:15 PM, 12/26/2021 4:30:45 AM, 1/7/2022 4:24:34 PM, 2/2/2022 11:04:24 PM, 2/8/2022 5:50:06 AM falls between 1/30/2022 5:09:41 PM and 2/8/2022 5:50:06 AM.
IsImprovementStdDev: Marked as improvement because 10.868598694124852 (T) = (0 -87898992.62281835) / Math.Sqrt((20148723021035.082 / (299)) + (3809235585864.156 / (31))) is greater than 1.9672228266464409 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (31) - 2, .975) and 0.05117478330012748 = (92639815.084744 - 87898992.62281835) / 92639815.084744 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
