Borgata AM Tournament (and others?)
 

I played this two weeks ago.

There were only about 90 (88?) entrants, but it took the tournament nearly an hour (58 minutes to be exact) to take care of the rebuys and add ons after the first 3 rounds.

I entered this tournament once before, along with 132 other fish, and this part only took about 20-30 minutes.

Which is the norm? Why would it take them so long? Are other tournament staffs more efficient or do they take this long as well?
