Quite frankly the DA is as totally different from the MA as the MA is from a scenario. It has little to do with flying. Its repetition of a certain move, usually with the same aircraft involved, co-alt,co-e states, and usually no worry of headon.
Followed by the winner either being cordial to the loser, or thumping his chest, and the loser either being graceful in defeat, or stating every reason why he lost...except being outflown.
Ok that last part was alot like the MA.
