Nope, I think you did quite well, Dazey!
I think you're right that verbally GT kids can often handle more sophisticated ideas presented in a more concentrated form, but they don't often get it. It's why I think verbally GT kids sometimes have a tougher time than mathy kids. A teacher can often give harder math problems without too much trouble, but they almost never assign a GT child a harder book for discussion or give more complex comprehension questions. That sort of differentiation just doesn't happen. The stuff the blog author wrote about verbally GT kids losing ground in reading during the school year and regaining during the summer is both right on target and terribly sad, I think.
I think maybe it has something to do with the fast vs. deep GT kids. For the deep and verbal kids, they need more, not just the same stuff faster. That just doesn't appeal to their strengths. In fact, faster can actually handicap them since they can't keep up and need time to mull things over. But a different, more sophisticated presentation of info plays to their strengths, gives them something to chew on.
So, yeah. I hear you!
