Spitoon,
Thanks for the time and explanation. I know there is a myriad of conditions that drive the DP and AR sep/spacing.
Here is what I am not quite understanding. Everything that I have, such as doc 4444, states that there is WT separation between heavies.
Again, excuse me for being dense on this, and I understand there are conditions that can reduce time based sep, such as immediate turns...but this table and the associated WT section, sure make it seem as though there is min WT spacing, even between heavies...
Really, I do want to understand this....
What am I missing here?
