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 6/22/2023 12:06:43 AM, 7/14/2023 7:13:27 PM, 7/25/2023 11:29:56 AM, 7/26/2023 10:32:59 PM falls between 7/18/2023 9:59:03 AM and 7/26/2023 10:32:59 PM.
IsImprovementStdDev: Marked as improvement because 9.975098911619211 (T) = (0 -76.82746624851865) / Math.Sqrt((54.04837218420811 / (299)) + (4.388501650146029 / (2))) is greater than 1.9679296690655894 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (2) - 2, .975) and 0.1667318680222712 = (92.20017338977276 - 76.82746624851865) / 92.20017338977276 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
