My aircrafts procedure is to depressurize at 25,000 if there is not a suitable landing site for an immediate descent and landing (e.g., midway between HNL and LAX).
I would feel a lot better about that procedure if there was more information or if depressurized flight at 25,000 has previously been used and resulted in a successful outcome.
I guess you could say that there has not been an example where depressurizing at 25,000 has not been successful.
