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 5.529357439424532 < 5.806923111702331.
IsChangePoint: Marked as a change because one of 11/13/2021 6:25:31 PM, 11/17/2021 2:42:53 PM, 12/2/2021 8:37:26 PM, 12/7/2021 12:20:12 AM, 12/17/2021 7:05:08 PM, 1/11/2022 2:18:34 PM, 1/18/2022 5:19:20 AM falls between 1/8/2022 8:22:56 PM and 1/18/2022 5:19:20 AM.
IsImprovementStdDev: Marked as improvement because 18.17580354052313 (T) = (0 -5569.084652952851) / Math.Sqrt((68801.59975659104 / (299)) + (3237.484401613351 / (33))) is greater than 1.9671786747533526 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (33) - 2, .975) and 0.05582625156390811 = (5898.368454087351 - 5569.084652952851) / 5898.368454087351 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
