Description of detection logic
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.
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 we could not find enough baseline builds for window checking.
IsChangePoint: Marked as a change because one of 5/19/2023 4:22:12 AM, 5/28/2023 7:57:15 PM, 5/30/2023 4:48:39 PM, 6/7/2023 7:43:49 PM falls between 5/29/2023 5:51:10 AM and 6/7/2023 7:43:49 PM.
IsImprovementStdDev: Marked as improvement because 5.003435824039125 (T) = (0 -305743.6271079525) / Math.Sqrt((237079412.71195933 / (299)) + (561030999.8122572 / (16))) is greater than 1.9675720194858106 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (16) - 2, .975) and 0.08924830462200542 = (335704.70267536305 - 305743.6271079525) / 335704.70267536305 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
