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 48.481074402507154 < 49.40316400135235.
IsChangePoint: Marked as a change because one of 3/10/2022 1:12:51 AM, 3/17/2022 6:54:53 PM, 3/30/2022 6:37:35 PM, 4/5/2022 2:02:34 AM falls between 3/26/2022 9:07:40 PM and 4/5/2022 2:02:34 AM.
IsImprovementStdDev: Marked as improvement because 15.525830508788761 (T) = (0 -49.068719179032804) / Math.Sqrt((1.3424816797459178 / (299)) + (1.325987179343312 / (24))) is greater than 1.967381707010986 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (24) - 2, .975) and 0.07178428191276245 = (52.86348660432954 - 49.068719179032804) / 52.86348660432954 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
