I guess that, as to whether to apply to DYS, it would depend on whether you think that the other pieces of the application would be strong and whether you think she really needs the support/advocacy. I have one dd with similar FSIQ and GAI scores for whom we have not applied b/c she does not have supporting achievement data, is 2e, and I'm not positive that she's the population they're aiming to serve or would be inclined to accept.
There is always that range of error on any test. If you feel like 146 is the lower end of her personal "range" and not the upper, it might be worth going ahead and applying.
On a side note, I've heard a few people here mentioning lower comprehension scores and the tester substituting information, which came in higher. That has me wondering b/c my dd was twice much, much lower on comprehension on the WISC-IV than the other two indices but never given any of the optional substitute tests. Not enough of a reason to retest, but it does make me curious how she would have done on something else.
