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 1.2223736251223356 < 2.224676325173692.
IsChangePoint: Marked as a change because one of 12/28/2022 7:19:51 AM, 1/5/2023 2:25:12 AM falls between 12/27/2022 1:08:06 PM and 1/5/2023 2:25:12 AM.
IsImprovementStdDev: Marked as improvement because 33.352393542236015 (T) = (0 -1.3538396594170758) / Math.Sqrt((0.05935713202882571 / (299)) + (0.011322950379497515 / (20))) is greater than 1.9674756580274855 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (20) - 2, .975) and 0.4051984952825803 = (2.276120098351571 - 1.3538396594170758) / 2.276120098351571 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
