i used to take girt's queue on this being a 6/3 split, not a 3/3/3. i even tested the 3/3/3 theory myself and am 100% positive its not like that. however, i think its actually 4/2/3 with a low, medium, and high threshold. im pretty much 95% sold on this, even though i never tested it to verify it myself, like i did the 3/3/3. the complete list of the 9 messages is somewhere, on these forums, i think in multiple places actually.
i take this as one of the two medium messages. if you think of it as low, med, high, the messages are self explanatory.
