V1-VR, a scary place to have a problem...if that number could be shrunk down a little, less exposure, somehow with more thrust, or changing flap positions, ect I might feel a little better trying to 'find' VR if I am committed after V1.
If that's a real issue with you (I'd like to see statistics supporting this), and if you have a range of V1's available, I suppose this could bias you to V1max.
But in the 2008 airline universe - Is it a significant issue? (I'll acknowledge that fewer tires on your bird might alter the picture)
