I don't think this will surprise anyone who has looked back at last year's result's forum information, but there is a definite trend towards a lower acceptance/rejection ratio as the season goes on. Here are the numbers I put together from last year (just doing a ctrl+f on the results page, broken down into 50-item chunks).
12 Jan - 16 Feb:
20 accept / 11 reject = 0.64
17 Feb -24 Feb:
21 accept / 22 reject = 0.49
24 Feb -27 Feb:
12 accept / 25 reject = 0.32
27 Feb -2 March:
9 accept /32 reject = 0.22
2 March - 5 March:
11 accept / 32 reject = 0.25
5 March - 10 March:
14 accept / 28 reject = 0.33
10 March - 12 March:
5 accept / reject 36 = 0.12
12 March - 18 March
9 accept / 36 reject = 0.2
Doesn't tell you anything about your schools, of course, but it gives you the general trend. There does seem to be a little boost around the 3-10 of March, which I'm assuming are wait-listed acceptances, but who knows.
