Are you in-state for GTech?
I don’t know about Cornell and Vanderbilt, since the acceptance rates keep falling. However, looking at @Eeyore123’s stats, and since your DD is a legacy, it could easily also be a match or low match.
The Vanderbilt seems odd, but data is data, and even if it’s a relatively small data set (say a total of 40-60 applicants in the past three years), it would indicate that high-stats kids from your DD’s HS are being accepted at a higher rate than expected, even if all the applicants were applying ED.
I wouldn’t think of them as matches in your expectations, but if I were you, i would feel comfortable with adding them to a list that already had three or four reaches without considering the list to be “reach heavy”. Personally, if it were me, I would put together a list with reaches and matches that were clearer, and then add those on as “extras”. But that’s me thinking what I would have done, but since I never had to make those decisions, you can take my advice with a couple of handfuls of salt.
