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 18.577889963199244 < 773.7927520195861.
IsChangePoint: Marked as a change because one of 10/26/2022 7:11:30 AM, 11/1/2022 10:15:31 AM falls between 10/23/2022 1:14:54 PM and 11/1/2022 10:15:31 AM.
IsImprovementStdDev: Marked as improvement because 382.2154063289702 (T) = (0 -18.063979076332974) / Math.Sqrt((1390.8477317713182 / (299)) + (1.2884886719058126 / (27))) is greater than 1.9673127716992511 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (27) - 2, .975) and 0.978663746959387 = (846.6331479078655 - 18.063979076332974) / 846.6331479078655 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
