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 3.566848099791647 < 4.428203519733632.
IsChangePoint: Marked as a change because one of 5/11/2022 7:02:26 PM, 6/2/2022 5:58:32 PM, 6/7/2022 9:00:42 AM falls between 5/29/2022 5:15:01 PM and 6/7/2022 9:00:42 AM.
IsImprovementStdDev: Marked as improvement because 14.35990206770708 (T) = (0 -3.6331812790856253) / Math.Sqrt((0.20756121912260514 / (299)) + (0.02255889461774618 / (30))) is greater than 1.9672451058622664 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (30) - 2, .975) and 0.13066464642181855 = (4.179263231538282 - 3.6331812790856253) / 4.179263231538282 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
