Old Smokey, very interesting reading (revision for me....). I understand your point of the lower screen height (the accel go case) being less desirable if the runway is damp.
I often go down that route because of the Accel Stop case. If the runway is damp, the concessions allowed for a truly dry runway will be used (if dry perf is taken), because it is damp. Some may say that is what the concessions are for.
I would rather be sure of adequate Accel Stop performance and take the lower screen height, afterall, although lower its still safe. So my question is, although a lower screen height is used, what is wrong with using it??
