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.
IsRegressionWindowed: Marked as regression because 125.64555176494972 > 124.44072644704792.
IsChangePoint: Marked as a change because one of 9/6/2022 1:06:44 PM, 10/25/2022 2:34:53 PM, 10/31/2022 4:38:04 PM, 11/8/2022 2:29:58 AM falls between 10/30/2022 12:44:54 AM and 11/8/2022 2:29:58 AM.
IsRegressionStdDev: Marked as regression because -38.33955249148411 (T) = (0 -125.32261968017002) / Math.Sqrt((0.46385682761922326 / (19)) + (0.10030479256099278 / (11))) is less than -2.048407141790485 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (19) + (11) - 2, .025) and -0.05934521179082898 = (118.30196453931333 - 125.32261968017002) / 118.30196453931333 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.
