Crash said:GT2ETR, you don't understand. What Markus has stated is completely correct. A car travelling at 300 km/h is covering 83,1 metres per second, thus your 166,2 m difference speculation. However, there is a huge problem with such speculation. First of all, your deduction demands that the first car is doing 300 km/h while the other vehicle is standing still - things just don't work this way.
Crash, I will not comment on style and will keep this technical.
You and Markus are missing the point. When RUF says that by shortening 6th gear you will gain 2 seconds on a 0-300kph run, they are wrong, and if it was HP Lieb, with all my respects, he is wrong too.
Markus subsequently changed to say that the 2 seconds was as a result of changing ALL the gears, that stands a slight chance of being more accurate, but nevertheless very unlikely too.
Don't get too involved in theory, other than Speed = distance/time, and that will not change!! Standing still or not, 2 runs with different cars, at different times on different roads, all of this does not matter, Speed = distance/time. That distance will vary somewhat depending on the acceleration rate of both cars between speeds, but will not change much!
TB993TT has posted a graph showing two cars running up to 300kph with a time difference of less than 2 seconds, and a distance of over 100 meters, this should be proof enough for you, regardless if the runs were made at the same time or not, that is totally irrelevant, physics are physics!
In case this is not enough for you and Markus to believe, I can post another 10 graphs showing cars running from standstill to 160kph, or 200kph, or rolling starts from 100-200kph etc, and you will see that the physics prevail!
Here are some FYI:
Car A: 0-160kph in 7.47s- Distance: 162 meters
Car B: 0-160kph in 9.63s- Distance: 256 meters
Difference: 94 meters in 2.16 seconds at 160kph.
Car A: 100-200kph: 5.6 s- 246 meters
Car B: 100-200kph: 6.4 s- 274 meters
Difference: 28 meters in 0.8 seconds at 200kph
Car A: 100-250kph: 12.1 s- 634 meters
Car B: 100-250kph: 15.7s- 782 meters
Difference: 148 meters in 3.6 seconds at 250kph
Let me know if you would like me to post any of the data above.
I can also get entangled with you on formulas and exact acceleration rates of the RT12 in the last 100kph (200-300kph) etc.. but I do not see the point, if you are not willing to accept all the proof and data presented to you, there is not much one can do to convince you.

Crash said:....a distance of 30 metres (around 5 car lengths) seems conceivable to me and Ruf are most likely telling the truth...........Please, correct me if I missed anything.
No, it is not possible, and I hope the correction came from the data posted above.
If all the above is not enough, I strongly suggest you get in your cars and do some real life tests with data at hand.
