Hey there-

I emailed the psychologist who tested my kids, asking her if she could provide the raw scores for their WISCs. She actually had already gone through her high scorers and figured the extended scores, so was happy to send me the changes. Scores for both my son and daughter went up, though it was actually much more dramatic in my son's case. This was interesting, as their full scales had been almost identical, and now they are six points apart. My son's GAI went way up too, so it is now 13 points over my daughter's.
