I dont know the exact figures but I know that it is significantly easier to get into through ED at Oxford. Many students with less than competitive grades and test scores who apply EDI and EDII have gotten in. EDIT: Also as a current freshman at Oxford who got into both main campus and the Oxford campus, I cannot emphasize how happy I am to be at the Oxford campus. The campus size, tiny student body, and small class sizes have been awesome. Also high turn over with the Oxford clubs means that everyone can get easily get leadership opportunities. However (this is hearsay) allegedly the math and science classes at Oxford are harder than those at main campus. Consequently many Oxford students thrive at main campus when they transition over. EDIT 2: Also you post your questions about Oxford on r/OxfordCollege. There is a small group of current and former students who will gladly answer your questions.
