```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.
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 55.794840238634215 > 53.65630255194427.
IsChangePoint: Marked as a change because one of 11/16/2022 6:51:59 PM, 11/22/2022 2:20:42 AM falls between 11/13/2022 1:28:42 PM and 11/22/2022 2:20:42 AM.

### Description of detection logic
```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.
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 76.08090483370748 > 71.21295554222509.
IsChangePoint: Marked as a change because one of 11/16/2022 6:51:59 PM, 11/22/2022 2:20:42 AM falls between 11/13/2022 1:28:42 PM and 11/22/2022 2:20:42 AM.
IsRegressionStdDev: Marked as regression because -67.12103752493084 (T) = (0 -75.16506090517119) / Math.Sqrt((0.17579881714876913 / (29)) + (0.15323080500736208 / (24))) is less than -2.007583770314729 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (29) + (24) - 2, .025) and -0.11064847262026335 = (67.6767336904001 - 75.16506090517119) / 67.6767336904001 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 not as a regression because Edge Detector said so.
