Yaah, why don't you merge this guys two threads. He is just asking about conference frequency.
8 hours in 4 months seems a little low unless you are excluding everything that is not a formal lecture.
(we had a bit of a disagreement of what is intended by didactic, not that long ago)
I think of any lecture/conference that is designed to impart knowledge to residents as 'didactic', which includes unknowns cases, interesting case reviews, etc..
Some working conferences don't really count (most tumor boards for example)
8 hours in 4 months is really light, that is under 30 min a week. Especially when you combine it with Unknowns only 2 a month.
