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 60.268673385714294 > 56.406486060000006.
IsChangePoint: Marked as a change because one of 8/1/2022 8:26:50 AM, 10/2/2022 11:57:04 PM, 10/10/2022 9:53:50 PM falls between 10/2/2022 5:38:34 AM and 10/10/2022 9:53:50 PM.
IsRegressionStdDev: Marked as regression because -9.647735772549213 (T) = (0 -59777.55635195284) / Math.Sqrt((3227223.769564675 / (18)) + (1263772.8002527484 / (32))) is less than -2.010634757623041 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (18) + (32) - 2, .025) and -0.08165502387663268 = (55264.89965137972 - 59777.55635195284) / 55264.89965137972 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.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
