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 129.87339 > 128.2436575.
IsChangePoint: Marked as a change because one of 4/6/2023 1:55:21 PM, 4/25/2023 6:46:56 PM, 5/2/2023 10:35:24 AM falls between 4/23/2023 8:38:14 PM and 5/2/2023 10:35:24 AM.
IsRegressionStdDev: Marked as regression because -33.405632937012996 (T) = (0 -130133219.77207978) / Math.Sqrt((579305291704.907 / (23)) + (762904998089.2333 / (27))) is less than -2.010634757623041 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (23) + (27) - 2, .025) and -0.06308786173390701 = (122410596.95652172 - 130133219.77207978) / 122410596.95652172 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.
