Using Countermeasure Pack V3.02 my results are showing a small number of various countermeasures analyzed as having a negative severe crashes reduced per 100m . . . the value is not consistently negative for the countermeasure in general just occasionally. . . is this a problem with calibration or with the algorithms?

I never saw negative countermeasures before V3.02.
