I'm interested in hearing how your DS7 does compared to other data you have. GS9 did not do as well in some areas as I expected. A couple problems with it that I saw, we're working on a laptop with about a 12 inch screen. The small screen messed with his visual/spatial results. I don't have a mouse hooked up, we're using the touch pad and I heard him say 'oops' a couple times. There didn't appear to be any way to correct 'oops' when accidental clicks are made.
Also, it's very verbal, and we had some noise interference.
Other areas, like processing speed and working memory, was very high, I wouldn't have guessed that after telling him to do several things and only getting a response on one of the items!
