The only one. If i remember correctly, most of the cars scratched the 370 barrier, topping at a high 36X.
But again, that is actually an incredible speed, that's why i was trying to explain it earlier as the result of a bug on the transmitted data, or the advantage that BMW took from someone else's wake, or a particular engine mapping BMW wanted to try for that run, ...(or even a lapsus of the commentator saying 380 instead of 370 and fooling our sight...who knows...)
PS: isn't that the actual meaning of often invoked word "unofficial"...?
