DS8 has a similar spread, mamaandmore, and like gratified3, I tend to see issues with speed. He gets wiggy when he has to race to finish something, and this actually makes him perform slower than he would if there were no time limit. I don't think that's perfectionism, exactly. More like stress causing him to be unable to concentrate.
I don't see that my particular child needs much repetition, but I can certainly see how that might be possible in a kid like this. It is something to watch for, though I wonder if that may have more to do with working memory, maybe? Or how working memory gets moved to long term memory? Not sure...
For me, I think of the speed issue as part of DS8's asynchronous development, as is so often visible in GT kids. He is as deep as a kid several years older, but he processes things at the speed of an average child his age. It can be a bit of a roadblock at times, especially if a teacher doesn't understand that "smart" and "fast" aren't necessarily the same thing. When he was in public school, we did hear "How can he need harder material if he doesn't finish the material I give him?" It can be a challenge.
If it helps to make you feel any better, I have seen improvement in DS8's speed over the past couple of years, just as I would expect to see improvement in any child as he got older. He's still not going to win any races, but he is progressing normally and the mismatch seems to matter less as he gets older.
