About 2700 ft to get to V1...that leaves 6000 ft left over...
Your mantra ever since you played as ssg...what did you come up with for an accelerate-stop distance...and based on what data? You claim to be a single engine "jet pilot" of late...whereas you don't fly the LR60 or other two-pilot aircraft, what data did you use? The distance to V1 isn't particularly meaningful. The distance to get there and stop, or to go...is.
Then again, your experience is on the microsoft flight simulator, and mishaps are relatively painless there.
