Ditto to Grinity, elementary can be really rough. I know it's not much of a consolation, but it's taken us three years to get to something that I think it close for our DS7. Each year we'd make incrementation progress at a mind boggling (slow) pace, and it wasn't until about 6 weeks ago that I'd say we're in a good place.

Sorry to not be of more help other than the BTDT variety.
