I have developed quite a skill at applying the elastics - I can even slip 'em in without looking, or while walking down the street! (It has to be a quiet street, though, with nobody looking.) I can feel them pulling on my teeth, and the upper and lower teeth are slowly getting straighter and more aligned.
The ortho says the next stage is to get the upper teeth rotated out a bit more, as they still slant inwards a bit, then try to close up the holes. (I am still wearing a power chain, but so far it doesn't seem to be having much effect.)
