I misspoke, I'd say most people over the age of 45 who interview you. The bump to an average of 240 is pretty recent (last 10-15 years). I have heard that the reason why scores in all steps increased so much yearly is thy essentially we all use the same prep material for the test and the way test questions are kept is dependent on how often candidates get the question right (say they throw out questions where people get it right 20% or less and when everyone gets it correct at 80% or more). So in short, a 240 in 2005 is the same exact performance as a 240 in 2015, however, test prep is that much better and people know what little facts to memorize for the test. As more people utilize the same test prep material, the score rises. Why 95% of Step 1 is first aid, it's because no one knows anymore random knowledge except what's in that book and/or pathoma (at least when I took it).
Anyhow, most PD are not going to reject him for an above average step score (guessing low 240s means greater than 240). It is going to be his away rotation and clinical grades/rank/other things brought to the table. Step 2, regardless if he releases it now, might be used to rank him against other similar applicants once he does interview. The reason why it's usually not a screening factor is not everyone takes it, even if it is a better predictor of medical knowledge for IM.
