Description of detection logic

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.
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 93.8067525548623 > 78.1986461298077.
IsChangePoint: Marked as a change because one of 1/13/2023 9:23:19 AM, 3/17/2023 5:40:49 AM, 3/25/2023 12:18:49 AM, 3/30/2023 4:24:24 AM falls between 3/21/2023 2:53:21 PM and 3/30/2023 4:24:24 AM.
IsRegressionStdDev: Marked as regression because -24.345292438042073 (T) = (0 -92.92124544278508) / Math.Sqrt((0.4761242123680715 / (22)) + (9.688559887847028 / (17))) is less than -2.026192463026769 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (22) + (17) - 2, .025) and -0.252365131071706 = (74.19660859071358 - 92.92124544278508) / 74.19660859071358 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.
