Oh yes. DS12 has a 64 point spread. His VCI was 152 (no extended norms done) and his PSI was 88.
He had hand pain when writing when he was younger and still has cramping when he writes a lot. He was late to tie his shoes, manipulate buttons etc. His hand writing is neat and small and his written expression isn't anywhere near as complex and deep as his verbal expression. He used to freeze up during timed tests and though he was first admitted to the AIG program in first grade (identified for other reasons by his kindy teacher) due to his math ability, he took minute math tests the whole of second grade and his time never changed.
He was resistant to memorizing math facts, and I don't know why. He's not a lazy child. He despises repetition however, and I have a feeling that early on he learned to hide certain things about himself.
