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 630.7534076923077 > 592.4936500000001.
IsChangePoint: Marked as a change because one of 11/17/2021 12:07:43 AM, 11/18/2021 5:43:05 PM, 12/9/2021 12:47:15 PM, 12/27/2021 6:47:12 AM, 1/4/2022 2:24:22 AM, 1/11/2022 1:49:04 AM falls between 1/1/2022 6:33:38 PM and 1/11/2022 1:49:04 AM.
IsRegressionStdDev: Marked as regression because -30.66812035458578 (T) = (0 -620495466.5018315) / Math.Sqrt((15742585632003.957 / (20)) + (98739365116856.03 / (41))) is less than -2.000995378087428 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (20) + (41) - 2, .025) and -0.09691342782679249 = (565674054.8168497 - 620495466.5018315) / 565674054.8168497 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 not as a regression because Edge Detector said so.
