1. the majority of my classmates - 90% are overall pretty chill
2. the people who do seek out opportunities is because they are truly interested in the subject matter, want the additional experience, exposure, and NOT because they feel the need to distinguish themselves. Of course, there's always 5-10% of people who's reasoning is that, but that's everywhere. in addition, stanford seeks truly outstanding, creative, and independent individuals, who are not just content with being medical students. the people that chose to come to stanford are into more than just learning medicine, and will have a broad range of interests....
3. only 65 student entered the match because given our wonderful clinical yrs flexibility people discovered new interests in their clinical yr, and decide to do something else, which may add another 1-2 yrs....of either doing international work, having a family, starting a new company, doing clinical or basic science research, working doing something else before they enter their residency works, writing books, novels, working for govt, getting MPHs, PhD, JDs, MBAs, M.Ed.....
😍 😍 etc.....
4. the % of people who take time off varies, and I would not be able to concretely state that only 75% take 5 yrs. i am not able to speak on behalf of those who take 4 vs. 5 and compare their match list results...my guessing is that they do, but those are prolly the classmates that are not chill. LOL

b/c they are forced to be gunners
hopes this helps,
