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 we could not find enough baseline builds for window checking.
IsChangePoint: Marked as a change because one of 10/10/2023 9:10:48 AM, 10/18/2023 4:42:02 PM falls between 10/9/2023 8:09:24 PM and 10/18/2023 4:42:02 PM.
IsImprovementStdDev: Marked as improvement because 12.417880348568662 (T) = (0 -10.799122513043036) / Math.Sqrt((0.9953560682793188 / (299)) + (0.6049786204129345 / (12))) is greater than 1.9676708853560316 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (12) - 2, .975) and 0.21047067546966233 = (13.677924527334108 - 10.799122513043036) / 13.677924527334108 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
