Congrats !!! Borrowing your case it sounds impossible for people who havent been admitted yet to get admitted at all..it took them 3 days between the "Recommended for Admission" and the "Admitted" mail...
On a more serious note, it doesn't look good with the numbers (23 invited to interview and 10 in already) I doubt acceptances go way higher than 50% of those interviewed in R3. Last years numbers seem to agree. I wager no more than an additional 2-3 admits at the most on this forum.
But I'm happy to be proven wrong
I suppose the days and weeks after April 18th will reveal much more, as R2, and R3 need to firm their acceptances with deposit $. I see so many admits here who have accepted to other equally placed schools so exciting times ahead for wait-listers and waitlisters-to be.
Also I think they will wait-list internationals in R3 because they will only know of R1, R2 deposit acceptances by Apr 18th.
