aeh, thank you very much. That explains quite a lot in our case - there are good reasons she would not have been at her best at 9, it just didn't make sense that she would look so uniform. Fine motor is a particular weakness, and her memory in general was worse that spring than usual, seen in all her testing and in daily life. I'm relieved to put that mystery to rest. Hopefully this comparison will help the OP, as well.
