Why is there a numeric id before the user id in my changes?
I have rows in my change history where the User account is preempted by a numeric ID and two @ symbols.
Why the extra prefix? Is this a change that was made internally by adwords staff?

No, this is a bug that happens from time to time in the Adwords Online UI. It will probably go away on its own. The Google Adwords Online UI is not the most stable program (they push live code updates all day long).
Last week I was getting click through rates in the 1000s.
