IsChangePoint: Marked as a change because one of 1/11/2022 2:18:34 PM, 1/18/2022 7:04:48 PM, 3/11/2022 8:42:43 PM, 3/15/2022 12:53:39 AM falls between 3/6/2022 12:59:26 AM and 3/15/2022 12:53:39 AM.
IsRegressionStdDev: Marked as regression because -14.02701433603456 (T) = (0 -149.61656383692844) / Math.Sqrt((10.55722883064997 / (50)) + (7.107666420398533 / (12))) is less than -2.0002978220134566 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (50) + (12) - 2, .025) and -0.09174588306105283 = (137.04339641513587 - 149.61656383692844) / 137.04339641513587 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.
