Here is the link to the 2013 SOAP thread, a genuine soap opera with over 1,100 posts and advice by people who have massive student debt an no job after residency. Reading it in real time was the ultimate

last week.
Of course it includes Americans, Americans who went to foreign medical schools, and foreign people who went to foreign medical schools. Why? Because those are the people who are applying to the match. And when they don't match, they are the people who are trying to SOAP into the remaining unmatched positions.
Your table 7 shows that in 2013 there were only 26392-25463=929 positions that did not fill in the original match, over a 15% drop from last year's 1,100 positions.
I am only disputing your original statement that "
There are open residency spots every year". I am saying that after the match and post-match process there basically aren't open spots available on the March 15th match day, meanwhile there are thousands of MD and DO applicants from all walks of life (AMG, USIMG, FMG, re-applicants, etc) that have no residency options at all this year.
