Yes, this is how the input would scale. I'm sorry for not replying earlier to the solutions given so far (Andrew, David) - I must admit that I am still digesting the code given to extract and understand the underlying idea(s). For your (Andrew's) solution to example #1, am I right that the underlying idea could be paraphrased as: "Group by start, then tail-trim the resulting groups to end (using a nested grouping from end)"? I hope I can give a verbal write-up of the ideas behind the solutions for the other cases as well as soon as I have fully grasped them myself... -Christian
