I stopped using DME for my starters now that I culture/save the yeast strains. On mash out, I collect about a liter or two of wort to boil seperately, since the full batch boil takes a lot longer. I have a jam-sized mason jar of the yeast I'll be using, and once the liter or two is cooled, I pitch the yeast.
This makes the starter near identical to the full batch. Also, if you time it right, the starter yeast will be approaching full krausen just as you're hitting pitching temps post-boiling of the full batch. Forgot where I read it, but full krausen in the starter is the ideal time to pitch as the yeast are highly active and no longer dormant.
