Well, yes, the key word being subjective. My understanding is that these scales are there to push a kid in who is close but doesn't quite meet test score minimums and is clearly GT.

I wouldn't doubt that they've been used to keep a kid out, but I think and hope that's the exception, not the rule.

Well, whoever showed you the GBRS did you a favor because in the chance your daughter does not qualify you have a very solid case for appeal.
