UMC Annual Conference Clergy Executive Sessions

I noticed a UMC clergy Facebook friend post that their executive session was about to begin.  She expects it to to 4 1/4 hours!  I know that it's an essential beginning to an Annual Conference meeting with a lot of business to work through, but that's twice as long as our North GA clergy session.  It made me wonder what "normal" might be in most annual conferences.  What conference are you in and how long does your session go?  Is there something in particular, in addition to Board of Ordained Ministry report and the necessary voting, that makes up your clergy session?
