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 54.763132337580544 < 59.09226248764936.
IsChangePoint: Marked as a change because one of 7/2/2022 7:35:06 PM, 7/6/2022 3:55:24 AM, 9/10/2022 4:15:15 AM, 9/15/2022 1:10:12 AM falls between 9/6/2022 1:06:44 PM and 9/15/2022 1:10:12 AM.
IsImprovementStdDev: Marked as improvement because 15.207504022159533 (T) = (0 -49.16504838957303) / Math.Sqrt((125.38339120328445 / (299)) + (17.877366049950723 / (22))) is greater than 1.9674283869023508 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (22) - 2, .975) and 0.2555752580027524 = (66.04435024239805 - 49.16504838957303) / 66.04435024239805 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
