Do Coffee maker Line Jumpers spoil the whole pot?

Is there scientific proof that getting a cup of coffee from the coffee maker prior to the whole pot being brewed, messes up the flavor of the rest of the pot?
Impatiently Waiting....

This would be a fun experiment to do at the office on a slow day. Brew the pot of coffee and take samples throughout the brewing process, then do a blind taste test and you'll have your answer.

My gut feeling is that although the extraction from each stage of brewing will be slightly different, the similarities will override any subtle differences that there may or may not be, and so there would be no negative effect of a "line jumper"
