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 30.111012998100154 < 35.17047391072848.
IsChangePoint: Marked as a change because one of 4/12/2022 9:30:02 AM, 4/20/2022 10:05:23 PM falls between 4/12/2022 9:30:02 AM and 4/20/2022 10:05:23 PM.
IsImprovementStdDev: Marked as improvement because 94.92171184712187 (T) = (0 -30.36719203211754) / Math.Sqrt((0.4637353915075991 / (299)) + (0.08923176616814141 / (31))) is greater than 1.9672228266464409 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (31) - 2, .975) and 0.1722083964899267 = (36.68458571378588 - 30.36719203211754) / 36.68458571378588 is greater than 0.05.
IsChangeEdgeDetector: Marked as regression because Edge Detector said so.
