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 19.40727082412483 < 25.014459155156153.
IsChangePoint: Marked as a change because one of 1/25/2022 6:54:35 PM, 2/1/2022 8:13:55 AM, 2/24/2022 10:17:16 AM, 3/7/2022 10:45:01 PM, 3/15/2022 12:53:39 AM falls between 3/6/2022 12:59:26 AM and 3/15/2022 12:53:39 AM.
IsImprovementStdDev: Marked as improvement because 22.764864968402346 (T) = (0 -19365.864257616646) / Math.Sqrt((8656485.023426877 / (299)) + (18369.720885898216 / (36))) is greater than 1.9671134448822736 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (36) - 2, .975) and 0.16789424384047816 = (23273.32086608477 - 19365.864257616646) / 23273.32086608477 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
