What should my blitz rating be?

Ok, I have a 1450 rating in Standard 30 min. chess. However, when I play 10 min blitz games (and I've played hundreds of them), I am still only an 1100. I'm only playing them for the heck of it, I really don't care about the rating. 

Even still, am I underrated at blitz chess given my much higher standard rating?
