Old Smokey,
I like your approach so I have a little question for you.
There is a tendency to feel more comfortable with low V1. As a consequence one sees that people are inclined to use the wet RTOW in conditions that approach but are not quit like the wet scenario.
Taking into account that the wet screen height is much lower and the role the reversers play in the wet case, how would you explain how and/if any safety margin is eroded by this practise?
