IsChangePoint: Marked as a change because one of 3/4/2022 11:33:07 AM, 3/17/2022 6:54:53 PM, 4/19/2022 4:39:14 PM, 4/26/2022 6:18:08 AM falls between 4/17/2022 3:25:40 PM and 4/26/2022 6:18:08 AM.
IsRegressionStdDev: Marked as regression because -23.49943305153873 (T) = (0 -334125.05699912) / Math.Sqrt((36440405.893655024 / (23)) + (24886886.281951267 / (35))) is less than -2.0032407188469383 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (23) + (35) - 2, .025) and -0.11926477574388389 = (298521.9085243296 - 334125.05699912) / 298521.9085243296 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.
