System.Tests.Perf_Environment.GetLogicalDrives

Description of detection logic

IsRegressionChecked: Marked as regression because the three check build points were 0.05 greater than the baseline.
IsImprovementBase: Marked as not an improvement because the compare was not 5% less than the baseline, or the value was too small.
IsRegressionBase: Marked as regression because the compare was 5% greater than the baseline, and the value was not too small.
IsRegressionChecked: Marked as regression because the three check build points were 0.05 greater than the baseline.
IsRegressionWindowed: Marked as regression because 75.29920601415095 > 60.576887587982704.
IsChangePoint: Marked as a change because one of 5/24/2022 3:42:52 PM, 6/2/2022 10:01:42 AM falls between 5/24/2022 3:42:52 PM and 6/2/2022 10:01:42 AM.
IsRegressionStdDev: Marked as regression because -27.99982229578699 (T) = (0 -74448.40337007254) / Math.Sqrt((2493172.0681220302 / (11)) + (3510588.1230505556 / (34))) is less than -2.016692199226234 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (11) + (34) - 2, .025) and -0.2755428319235665 = (58366.05522513231 - 74448.40337007254) / 58366.05522513231 is less than -0.05.
IsImprovementBase: Marked as not an improvement because the compare was not 5% less than the baseline, or the value was too small.
IsChangeEdgeDetector: Marked as regression because Edge Detector said so.
