Here are other exceptions I would not add-on:
1) If the R/A tourney happens to have an overlay, it is in everybody's interest to minimize R/A. For example, when there was one table left at the end of the rebuy period, all the players agreed not to add-on.
2) In an R/A multiple-seat satellite when I have enough chips or in a good relative chip position to win one of the seats.
3) I won an entry to a high buy-in R/A MTT that I would not normally buy into, and I felt the remaining players in my table were too good for me to pay the high cost of the add-on.
4) If the add-on does not increase the prize pool. For example, some did not pay for the additional chips at the WPT Celebrity Invitational.
5) If nobody else adds on for some reason, I would not either.

Wetts1012;353335 wroteif the AO gives you an additional 5BB, whats the point.
Actually, I would usually AO in this situation. If most players AO for the 5 BB and I did not think that I was below average against the remaining field, then I would AO to remain competitive.
