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 644.708763527802 < 681.2758821597878.
IsChangePoint: Marked as a change because one of 1/22/2023 11:22:03 PM, 1/27/2023 7:12:54 PM, 2/9/2023 4:27:10 AM, 2/24/2023 9:01:57 AM, 3/6/2023 11:14:52 AM, 3/15/2023 8:07:42 AM, 3/21/2023 3:33:39 AM falls between 3/11/2023 9:11:51 PM and 3/21/2023 3:33:39 AM.
IsImprovementStdDev: Marked as improvement because 35.689100367624874 (T) = (0 -647.5214886598551) / Math.Sqrt((1181.0820412449532 / (299)) + (9.599566705242868 / (28))) is greater than 1.967290077109849 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (28) - 2, .975) and 0.10249361643470567 = (721.4672792494376 - 647.5214886598551) / 721.4672792494376 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.

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 1.1580168197815257 < 1.42131865648168.
IsChangePoint: Marked as a change because one of 1/5/2023 11:35:29 PM, 1/15/2023 2:31:53 AM, 1/30/2023 9:42:46 PM, 2/9/2023 4:27:10 AM, 2/16/2023 9:36:08 AM, 2/20/2023 10:31:48 AM, 3/6/2023 11:14:52 AM, 3/14/2023 8:42:09 PM, 3/21/2023 3:33:39 AM falls between 3/11/2023 9:11:51 PM and 3/21/2023 3:33:39 AM.
IsImprovementStdDev: Marked as improvement because 13.563092810358611 (T) = (0 -1159.1521422864073) / Math.Sqrt((26706.55807497513 / (299)) + (2.0036537208155534 / (31))) is greater than 1.9672228266464409 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (31) - 2, .975) and 0.09960513808277514 = (1287.3820046220683 - 1159.1521422864073) / 1287.3820046220683 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
