Yup. I am certainly not an expert on TX schools, other than knowing they are dirt cheap and have a requirement that at least 90% of their seats go to residents. Private schools like Baylor are not subject to that requirement, but still heavily favor IS applicants.
TX residents generally want to stay in TX, and so prefer TX schools. TX schools have far few seats than residents who want them, and the tuition is already heavily subsidized by the state, so they generally don't feel a need to get into bidding wars with schools like OSU for one of the 5 or so applicants who have such an offer. Even 50% off OOS tuition at OSU is still higher than IS tuition at every TX school, including Baylor!
Bottom line, very few TX applicants receive OOS opportunities that are cost competitive with their IS options. Forget OSU. The 250 or so that
@wysdoc referenced above are probably receiving generous need based offers at schools like Harvard and JHU, and TX schools are not bidding against them either.
TX is simply an island onto itself, with its own application system, a uniquely heavy IS preference, and the lowest IS tuition in the country, other than NYU and USUHS.
@throwaway01564's strategy is typical, because it's a waste of time and energy to go through the motions at schools they have no genuine interest in when their IS schools ideally position them for the residencies they want and when they are already benefiting from among the lowest COAs in the country.
Put another way, EVERY IS TX matriculant is automatically receiving around a 65% scholarship as compared to OOS tuition at just about every school in the country. In addition, I'm sure TX schools make additional financial aid available to those with demonstrated need. What more is there to chase, other than an acceptance at a school they'd really rather attend?
