IsImprovementBase: Marked as improvement because the compare was 5% less than the baseline, and the value was not too small.
IsImprovementCheck: Marked as improvement because the three check build points were 0.05 less than the baseline.
IsRegressionBase: Marked as not a regression because the compare was not 5% greater than the baseline, or the value was too small.
IsImprovementBase: Marked as improvement because the compare was 5% less than the baseline, and the value was not too small.
IsImprovementCheck: Marked as improvement because the three check build points were 0.05 less than the baseline.
IsImprovementWindowed:Marked as improvement because 12.159466032959875 < 518.6843055854379.
IsChangePoint: Marked as a change because one of 10/26/2022 7:11:30 AM, 11/1/2022 2:33:16 AM falls between 10/23/2022 1:14:54 PM and 11/1/2022 2:33:16 AM.
IsImprovementStdDev: Marked as improvement because 249.67139972459245 (T) = (0 -12.106932272250942) / Math.Sqrt((1472.7088547221044 / (299)) + (0.05274947838367812 / (26))) is greater than 1.967335607330539 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (26) - 2, .975) and 0.9786219548155796 = (566.3255067434329 - 12.106932272250942) / 566.3255067434329 is greater than 0.05.
