Huh? Rough translation as I understand the above. "I know what I said, but I really didn't know what I was saying, because I didn't know what I was trying to prove, I was trying to do wierd ('uncommon') stuff, and I shoulda been more specific with the words I used. No matter what solution was proposed, I was gonna re-write my stuff to be better ('iterative process')."

I guess I'm no longer eligible to be an arbitrator, then :)

Opinions (in no particular order):
- "Various" is not a number nor an objective criteria. (Does the expression "carrot and stick" ring a bell? It should, the concept has been used in this thread already.) - Hierarchies do not necessarily reflect the "real world." (I.e. how does this apply to the
real-world of "matrix-managed" organizations for example? Or is this just an academic exercise?_
- When you set a "challenge" without any *quantified* criteria for success, both the challenger and the responder open the door to pissing contests like we have seen here. Neo should have been more clear in *his" definition of normalized, etc. This may or may not have influenced Hugo's solution.

[I'm probably going to regret this post... oh well.]
