I know but, I try to find from where they came from and for example I couldn't find the 0-100mph of 8.3, a 8.36, yes, but that rounds up to 8.4, and the 0-200km/h I'm pretty sure is an assumption based on the 1/4 mile time of 11.8 @ 123.6mph by motortrend I think, I can't recall right now, but that time was never matched again in any test.
I do my research, obviously, and a 0-200 faster than 13.8 was inexistent in any sportauto, AMS, autobild, autozeitung tests, can you really believe that the '03 viper is faster accelerating than the C6 Z06? I don't.
The same can be said about the 0-100km/h, the fastest is 4.2 by sportauto, and then are some 4.3 and 4.5 times, but no 3.9, albeit, there were plenty of 3.9 0-60mph times from car and driver, motortrend and road and track.
I personally can't stand the use of 1ft roll out, 60mph=100km/h and so on, I can't, or maybe I'm having a little episode of OCD haha
