If it's reported as really high or really low, then it might be worth specifically inquiring about with the PD. But you're generally going to get a much more accurate idea by asking residents at, or recently from, that program. Programs who don't fill that part out may or may not have a good reason. Frankly, much of the time the admin/secretary filling in those blanks probably has little to no idea, particularly if they happen to be from over in GME and used to filling it in for med/surg. And, of course, some rotations may be very low-intensity in terms of in-house workload, while others (usually surgpath) require more time, so an overall "average" can be very misleading.
