Ummm....
well, I can tell you that the assessments in both K12 and Connections are not the greatest for gifties.
My daughter also spends HOURS and HOURS on assessments. (We're with Connections.)
The assessments are very lengthy. I think your concern is a valid one, and your 'read' on the situation is also valid. But if it's any consolation, your experience on the phone is also typical-- and it may not really mean much. The corporate folks are often fairly clueless, we've found. The educational-side people, on the other hand, have generally been pretty good to work with.
I'd still say that you should give it a try-- I'm not sure if it's an option for you, but be sure to look at Connections as well as K12 if you can, because Connections does have some experience with HG students, and their attitude about placement has been fairly flexible, in our experience.
