I noticed this was posted on the sf match website today and figured I would repost many have asked about this in the past. It looks like they made an error on the website statistics posting of 89% overall matching this year. Looks like 89% of allopathic seniors matched with an overall match rate of 78% of all applicants. Enjoy.
