Description of detection logic

IsRegressionChecked: Marked as regression because the three check build points were 0.05 greater than the baseline.
IsImprovementBase: Marked as not an improvement because the compare was not 5% less than the baseline, or the value was too small.
IsRegressionBase: Marked as regression because the compare was 5% greater than the baseline, and the value was not too small.
IsRegressionChecked: Marked as regression because the three check build points were 0.05 greater than the baseline.
IsRegressionWindowed: Marked as regression because 2.7235549697493515 > 484.58070972202694.
IsChangePoint: Marked as a change because one of 3/18/2022 2:15:20 PM, 4/7/2022 6:53:49 PM, 4/14/2022 3:36:10 AM falls between 4/5/2022 1:54:35 PM and 4/14/2022 3:36:10 AM.
IsRegressionStdDev: Marked as regression because -134.1745051363217 (T) = (0 -2835538.0816935166) / Math.Sqrt((161786258.14188233 / (20)) + (6731543143.445374 / (22))) is less than -2.0210753903043583 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (20) + (22) - 2, .025) and -5.195185204479093 = (457700.2927440223 - 2835538.0816935166) / 457700.2927440223 is less than -0.05.
IsImprovementBase: Marked as not an improvement because the compare was not 5% less than the baseline, or the value was too small.
IsChangeEdgeDetector: Marked as regression because Edge Detector said so.
