Description of detection logic

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 32.8357993745361 < 33.65805215362629.
IsChangePoint: Marked as a change because one of 5/31/2022 5:02:26 PM, 6/6/2022 8:15:49 PM, 6/9/2022 4:58:43 AM falls between 5/31/2022 10:47:41 AM and 6/9/2022 4:58:43 AM.
IsImprovementStdDev: Marked as improvement because 9.027129571264656 (T) = (0 -32.89937446401473) / Math.Sqrt((14.761897210229954 / (165)) + (0.0006131801869821201 / (9))) is greater than 1.9738521694944169 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (165) + (9) - 2, .975) and 0.07587313822475897 = (35.60049580294124 - 32.89937446401473) / 35.60049580294124 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
