Thanks, I read the thread and posted there first. Sorry for the dup, but the thread seemed to be getting so long that some questions get lost.

Anyway, by way of response, this seems very unfair as it is often unlikely that even a 1k will clear all segments in advance. I'll stop posting here and take it back to the other thread, but you thoughts would be appreciated on how to set up an itinerary to clear all segments initially.
