Here is a quote ifrom a previous reply of mine about what this really means, I added the words in brackets for contextual clarity:
As you can see 3.5 sigma is even orders of magnitude smaller than a 3 sigma event. A 3.5 sigma occurence is truly a one in a million event (okay a slight bit more rare, about 0.7 in a million - but you get the point).

So we can reasonably conclude that statistically, the 7:30 time is highly improbable for a "stock" GTR can achieve this time.
So...statiscally, Porsche is likely correct in its accusations.
I would love to see the beta software they had in the GTR.
