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 1.5576930217347555 < 1.7239793185782728.
IsChangePoint: Marked as a change because one of 5/11/2022 7:18:06 PM, 5/18/2022 4:10:31 AM falls between 5/9/2022 3:38:36 PM and 5/18/2022 4:10:31 AM.
IsImprovementStdDev: Marked as improvement because 39.26313762215386 (T) = (0 -1496.856181708264) / Math.Sqrt((717.2002016234572 / (299)) + (1819.9065947091049 / (26))) is greater than 1.967335607330539 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (26) - 2, .975) and 0.18246026259085282 = (1830.927737472344 - 1496.856181708264) / 1830.927737472344 is greater than 0.05.
