Description of detection logic

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.
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 34.8878325 < 47.35285360428571.
IsChangePoint: Marked as a change because one of 1/27/2023 12:48:15 AM, 4/17/2023 2:42:45 PM, 4/20/2023 5:25:38 AM falls between 4/11/2023 2:19:19 PM and 4/20/2023 5:25:38 AM.
IsImprovementStdDev: Marked as improvement because 30.76175946510647 (T) = (0 -33051540.1875) / Math.Sqrt((21536122396489.047 / (299)) + (2367623939205.067 / (8))) is greater than 1.967772354556772 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (8) - 2, .975) and 0.36085411781142357 = (51712044.32128114 - 33051540.1875) / 51712044.32128114 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
