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 we could not find enough baseline builds for window checking.
IsChangePoint: Marked as a change because one of 1/4/2022 12:37:46 AM, 1/11/2022 6:41:22 PM falls between 1/3/2022 4:56:39 AM and 1/11/2022 6:41:22 PM.
IsImprovementStdDev: Marked as improvement because 121.10480492694471 (T) = (0 -641.9149681920416) / Math.Sqrt((82860.03422575745 / (299)) + (1.015855508237965 / (16))) is greater than 1.9675720194858106 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (16) - 2, .975) and 0.758513549902535 = (2658.182137892051 - 641.9149681920416) / 2658.182137892051 is greater than 0.05.
IsChangeEdgeDetector: Marked as regression because Edge Detector said so.
