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 37.73298142857143 < 40.663749538412695.
IsChangePoint: Marked as a change because one of 10/27/2022 12:34:03 AM, 11/9/2022 4:06:23 PM, 1/3/2023 12:19:11 AM, 1/5/2023 2:25:12 AM falls between 12/27/2022 1:08:06 PM and 1/5/2023 2:25:12 AM.
IsImprovementStdDev: Marked as improvement because 35.18227289690549 (T) = (0 -37742142.45836168) / Math.Sqrt((3828079000948.8843 / (276)) + (426992174.2837378 / (6))) is greater than 1.9684724997369398 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (276) + (6) - 2, .975) and 0.09915089120501858 = (41896186.70861246 - 37742142.45836168) / 41896186.70861246 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
