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 48.685168694007054 < 50.62902563562232.
IsChangePoint: Marked as a change because one of 3/3/2023 10:27:59 PM, 3/9/2023 2:25:45 AM falls between 2/28/2023 7:22:28 AM and 3/9/2023 2:25:45 AM.
IsImprovementStdDev: Marked as improvement because 41.322919566843744 (T) = (0 -48.34100643282047) / Math.Sqrt((0.8541176792807232 / (299)) + (0.1747127498906509 / (19))) is greater than 1.9674995188240387 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (19) - 2, .975) and 0.08579252263843472 = (52.87750060012012 - 48.34100643282047) / 52.87750060012012 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
