Well, I realize I am not the only one at the airport. But I didn't say I was going to do a backtrack, holding everything up. I think it doesn't make a difference at all, if I am #6 holding at full lenghts or # 6 at the intersection - I will be number 6. And just to have the towercontroller have a nicer picture with aircraft evenly distributed over the various holdshort points is not my job.
When I am late I emphasize working slowly and with a cool head, I have caught myself too many times in the whirlpool of taxiing fast and rushing checklists. I won't do it anymore. So I do have the extra minute to taxi to full lenght.
And yes, I somewhat trust the performance calculations. At least, when done correctly and you still ended up in the grass, they make a pretty good excuse in front of the judge. But if I have a choice, why would I move along the edge of performance? It is legal to takeoff with stopmargin 0, but is it smart?
