Grant:

Rolling start does eliminate the launch advantage of the Turbo S, so that could have an effect...

Not at all. 991.2 Turbo S is way faster from let we say 60km/h to 160km/h then 991.2 GT3 PDK. Not to mention manual version. Something is clearly wrong with this video. If the 991.2 Turbo S driver used Sport + mode it would kill GT3 without any problem. Even latest AMG GT-S is faster on the roll then 991.2 GT3 PDK. So...
