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 269.65778603367437 > 248.3236066649993.
IsChangePoint: Marked as a change because one of 7/28/2022 3:42:13 AM, 10/11/2022 2:16:14 AM, 10/18/2022 8:25:03 PM falls between 10/7/2022 9:25:17 PM and 10/18/2022 8:25:03 PM.
IsRegressionStdDev: Marked as regression because -14.34095409310307 (T) = (0 -271.1522671687705) / Math.Sqrt((17.600888089904377 / (17)) + (33.81485919065937 / (8))) is less than -2.0686576104106944 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (17) + (8) - 2, .025) and -0.13807661635362764 = (238.25484442122743 - 271.1522671687705) / 238.25484442122743 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.
