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 6/3/2023 2:57:39 PM, 6/4/2023 9:29:52 PM, 6/7/2023 7:43:49 PM falls between 5/29/2023 11:58:32 PM and 6/7/2023 7:43:49 PM.
IsImprovementStdDev: Marked as improvement because 4.415457720680768 (T) = (0 -446046.9693311771) / Math.Sqrt((1655222338.1063075 / (299)) + (402441263.31217533 / (3))) is greater than 1.9679030112610798 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (3) - 2, .975) and 0.10474074397025786 = (498232.1783628212 - 446046.9693311771) / 498232.1783628212 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
