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 71.12071711448095 > 51.37175104774888.
IsChangePoint: Marked as a change because one of 10/11/2022 6:23:40 AM, 12/5/2022 3:14:07 PM, 12/13/2022 2:17:54 AM falls between 12/4/2022 6:53:17 AM and 12/13/2022 2:17:54 AM.
IsRegressionStdDev: Marked as regression because -30.042565700927085 (T) = (0 -74.16010821325703) / Math.Sqrt((6.582288291816523 / (20)) + (10.828568657684224 / (38))) is less than -2.0032407188469383 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (20) + (38) - 2, .025) and -0.46509830556410764 = (50.617837677931874 - 74.16010821325703) / 50.617837677931874 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.
