Yes, I would tend to agree with you that perhaps UGA is not in the “very generous” category that the other schools are. They’ve been slowly creeping up over the years in OOS selectivity (and have seen more high-stat applicants) so I’m guessing that their generosity in OOS merit will adjust accordingly.
They seemed to be more generous when my daughter applied OOS in 2013 (with lower stats). She also didn’t receive an award until mid-April (had already decided to go elsewhere), so there may still be a chance for your kid to see something. I believe I read on their admissions blog that they hand out awards well into April, once they see how the admissions numbers are looking.
