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 651.7985254876702 < 1.6906108728286446.
IsChangePoint: Marked as a change because one of 6/22/2022 5:33:38 PM, 7/10/2022 3:20:59 AM, 7/18/2022 2:17:16 AM falls between 7/8/2022 10:31:34 AM and 7/18/2022 2:17:16 AM.
IsImprovementStdDev: Marked as improvement because 148.35603765294354 (T) = (0 -641.7726232041672) / Math.Sqrt((27783.625118898166 / (299)) + (21.944109145495887 / (34))) is greater than 1.9671567996108528 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (34) - 2, .975) and 0.690983468535399 = (2076.8229458872324 - 641.7726232041672) / 2076.8229458872324 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
