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 we could not find enough baseline builds for window checking.
IsChangePoint: Marked as a change because one of 12/17/2022 10:44:50 PM, 2/28/2023 12:47:31 AM, 3/8/2023 2:17:54 AM falls between 2/27/2023 12:59:46 AM and 3/8/2023 2:17:54 AM.
IsRegressionStdDev: Marked as regression because -41.706063647368296 (T) = (0 -213.23083762401993) / Math.Sqrt((5.409036797828205 / (3)) + (24.123621801997235 / (6))) is less than -2.3646242515927898 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (3) + (6) - 2, .025) and -0.8939532399152861 = (112.5850591926744 - 213.23083762401993) / 112.5850591926744 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.
