And, FWIW, my dd's scores were gifted both times. It was just the difference btwn PG and MG with scores ranging from the 25th to 99.9th+ even when she appeared MG. I think that I might have been able to argue for GT placement even using the lower, MG, scores even if they had been a few points lower or missed the GT cut by a few points b/c there were some very impressively high scores still in there.
I'd agree with Nautigal that I wouldn't expect the kind of fluctuation we've seen in a non 2e child either and that type of erratic fluctuation is something we see constantly in dd in all of her testing including school tests and annual achievement tests. If you're not seeing that, which it doesn't sound like you are, I'd be less worried about a big change.
