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 5.9323080952380955 > 5.886711663636364.
IsChangePoint: Marked as a change because one of 7/15/2022 5:00:56 PM, 9/8/2022 6:17:28 PM, 9/13/2022 2:30:06 AM falls between 9/4/2022 8:45:57 AM and 9/13/2022 2:30:06 AM.
IsRegressionStdDev: Marked as regression because -19.274573056886705 (T) = (0 -5923687.616698998) / Math.Sqrt((4388914697.712178 / (39)) + (2144800438.9361887 / (19))) is less than -2.0032407188469383 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (39) + (19) - 2, .025) and -0.05136196025462187 = (5634298.976600202 - 5923687.616698998) / 5634298.976600202 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.
