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 123.8690432643196 > 121.64353494398283.
IsChangePoint: Marked as a change because one of 2/4/2023 8:08:12 PM, 2/7/2023 8:22:47 AM falls between 1/29/2023 5:12:48 PM and 2/7/2023 8:22:47 AM.
IsRegressionStdDev: Marked as regression because -22.44776606703201 (T) = (0 -123.29893489723182) / Math.Sqrt((4.974675668774219 / (48)) + (0.15448696851095828 / (11))) is less than -2.0024654592901125 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (48) + (11) - 2, .025) and -0.06661613902844353 = (115.59822731497577 - 123.29893489723182) / 115.59822731497577 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.
