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 5/5/2023 3:18:41 PM, 5/31/2023 1:59:31 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 24.64572538584695 (T) = (0 -479.59371195126545) / Math.Sqrt((1869.6206559362972 / (299)) + (259.6691873006134 / (14))) is greater than 1.9676211333067681 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (14) - 2, .975) and 0.20376943275948184 = (602.3301938951988 - 479.59371195126545) / 602.3301938951988 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
