Check page 11. Stats for Entering Year 2013 is 351/647, which is different than the 516/714 reported by A&M on Interview Day. Notice that at the bottom of the page it states "The offers stated are through Feb. 1 of each respective year and includes prematch offers and results of the match
. Somer offers were declined, others will be declined and
additional offers may be made from alternative list..
"
The report clearly states that this number >>351/647<< includes all applicants interviewed and all offers extended by A&M on that given year through Feb 1, but excludes offers made from the wait list.
I am confused as well and do not know which set of numbers to believe in.
