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.

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 67.86119457375908 < 70.96615696143655.
IsChangePoint: Marked as a change because one of 9/2/2023 3:43:46 AM, 9/12/2023 2:43:35 PM, 9/28/2023 11:34:37 PM, 10/2/2023 10:24:51 PM falls between 9/24/2023 12:29:05 AM and 10/2/2023 10:24:51 PM.
IsImprovementStdDev: Marked as improvement because 7.4735110553991815 (T) = (0 -67.71612909057546) / Math.Sqrt((12.431966135224808 / (177)) + (4.580344455468016 / (16))) is greater than 1.97246198976699 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (177) + (16) - 2, .975) and 0.06182330502183197 = (72.17843872379633 - 67.71612909057546) / 72.17843872379633 is greater than 0.05.
