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 2.255519691119691 < 2.4363333711340207.
IsChangePoint: Marked as a change because one of 7/17/2022 2:49:16 AM, 8/18/2022 3:00:51 AM, 9/8/2022 6:17:28 PM, 9/13/2022 2:30:06 AM falls between 9/4/2022 8:45:57 AM and 9/13/2022 2:30:06 AM.
IsImprovementStdDev: Marked as improvement because 8.34638676345476 (T) = (0 -2284310.369108606) / Math.Sqrt((3837861528.1505 / (299)) + (11815716466.25343 / (19))) is greater than 1.9674995188240387 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (19) - 2, .975) and 0.08429263744545683 = (2494585.565781714 - 2284310.369108606) / 2494585.565781714 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
