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 478.26944426406925 < 497.5295572797619.
IsChangePoint: Marked as a change because one of 10/6/2023 6:15:21 PM, 10/9/2023 8:09:24 PM falls between 10/1/2023 7:44:15 AM and 10/9/2023 8:09:24 PM.
IsImprovementStdDev: Marked as improvement because 20.792756437917685 (T) = (0 -476899.52307389304) / Math.Sqrt((177864048.85616827 / (210)) + (31189290.93591676 / (8))) is greater than 1.9710074720042792 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (210) + (8) - 2, .975) and 0.08674132657009162 = (522195.44905367336 - 476899.52307389304) / 522195.44905367336 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
