95% of the people who offer challenges to the DA are only looking for a fun fight, anyone who thinks they have other motives needs to check their head. 
I wouldn't agree with the percentage.
I think it's fair to say there is a small group of folks who go to the DA to sharpen their skills, but they are a seperate bunch from the crowd in the MA that thinks it will prove something. As I said in a previous post, I think those guys are in that phase of their AH cartoon flying career where it really matters to them and the challenge of being the 'bestest' they can be is important. Most of the ACM guys go through that stage at one point or another.
It's not a bad thing, but not everyone is that intense about it or has already been there, done that. More power to ya if you have the time and the energy for it

As for the other guys. They'll grow up and figure out it's just a game eventually
