I know how frustrating AP is because there seem to be no rhyme nor reason, but in this case, I am not sure how helpful the poll is going to be. AP averages vary greatly from one consulate to another even with in MENA. Even the average of one consulate cvaries over time depending on work load.
What might be the most helpful is to use the timeline search features and narrow the search for the consulate you are going through.
Good luck and keep in mind, that no matter how impossible this process is, there will be some resolution.
