Is there a limit on how many QB Regular Decision students colleges like Stanford take?

It seems like top tier colleges never want too many students from one “category,” so I am worried that if I go the QB RD route I will be locking myself out of the wider pool and will actually have lower chances despite whatever advantages I would have in terms of being recognized as a QB Finalist.

For example, Stanford seems to have a limit of 30? people for Match (from what I have read in various places, totally unconfirmed). I think that this is mostly because they want to see the entire applicant pool before they commit to a ton of acceptances, but perhaps it is also because it is expensive for them to offer full rides. Because they also basically offer full rides through the QB RD, will they have the same concerns and thus limit the amount of applicants they take from this category?

Bump, if anyone knows anything, even if you are unsure, please post.
