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 45.288528097982706 > 26.4814894877185.
IsChangePoint: Marked as a change because one of 1/25/2022 4:50:09 PM, 2/1/2022 5:51:01 AM falls between 1/23/2022 2:39:24 PM and 2/1/2022 5:51:01 AM.
IsRegressionStdDev: Marked as regression because -76.5504654674466 (T) = (0 -45553.52211875953) / Math.Sqrt((2233162.996507338 / (34)) + (651824.8880647082 / (45))) is less than -1.991254395387924 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (34) + (45) - 2, .025) and -0.9076578795741308 = (23879.29335050842 - 45553.52211875953) / 23879.29335050842 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 as regression because Edge Detector said so.
