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.
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 1.523722090088341 > 1.3869712789407886.
IsChangePoint: Marked as a change because one of 3/28/2023 2:42:21 AM, 3/30/2023 4:24:24 AM falls between 3/21/2023 2:53:21 PM and 3/30/2023 4:24:24 AM.
IsRegressionStdDev: Marked as regression because -151.23783962613393 (T) = (0 -1523.0959184507901) / Math.Sqrt((0.2804202603862349 / (33)) + (10.635993493740923 / (6))) is less than -2.026192463026769 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (33) + (6) - 2, .025) and -0.1527658033046314 = (1321.2535573874018 - 1523.0959184507901) / 1321.2535573874018 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.
