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 4.382217948350952 < 5.381281241239932.
IsChangePoint: Marked as a change because one of 4/25/2023 8:51:41 AM, 5/3/2023 7:05:50 AM, 5/9/2023 7:24:34 AM falls between 4/30/2023 6:17:41 PM and 5/9/2023 7:24:34 AM.
IsImprovementStdDev: Marked as improvement because 40.38642153848154 (T) = (0 -4.426762859011302) / Math.Sqrt((0.06450266342331673 / (299)) + (0.021247434920473058 / (16))) is greater than 1.9675720194858106 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (16) - 2, .975) and 0.2638673322315693 = (6.0135394784623974 - 4.426762859011302) / 6.0135394784623974 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
