The drop off happens more like 230s when you look at
the Tableau and you have to consider the numbers of people you're talking about. Most people with a score in the 220s that applied ortho matched, but that's a tiny fraction of a few dozen, and most of them probably only applied because they felt confident about matching at home or somewhere they did an away. There are doubtless many, many people who give up and don't even attempt to match surgical specialties any more because they score in the 220s or 230s and didn't feel they had that level of safety net.
Put it this way ace. If you took a well respected attending hospitalist at a major hospital, lets say an attending on the teaching service at MGH, do you really think they could take Step 1 tomorrow and score a 260+? Of course not. A huge component is details. Hell I had all the basic concepts understood at the end of preclinical and scored in the 210s on my first practice exam, then spent more than 2 months memorizing details out of First Aid and Uworld and climbed 40 points from doing so. You don't have to use Anki (I didn't either) but you
do have to walk into the test with an encyclopedia's worth of factoids that our best mentors do not possess.
