Well as Steve has climbed E11 this is an acedemic point.
> The thing that goves trad it's danger grade is how much you don't want to fall off. With sport the mentality is 'push yourself until you fall'. there for (without being stupidly pedantic) sport climbing is safe and has not danger grade and there for no trad grade.
There are trad routes of all grades where this is the case as well.
> Just a scientific way of looking at it.
I think you and I may have different definitions of scientific!
> like i say, when i reach the very best i can be at trad i may turn to sport, until then it's just a little training.
I'd venture to suggest that without doing a lot of sport climbing you will never 'reach the very best [you} can be at trad'. I'd be surprised if anyone has climbed E10 without having a pretty respectable background in sport climbing.
