PPB would count towards your AOW, as to would the DPV dive as long as you filled in the requisite Knowledge Review and it was signed off as an adventure dive. The Nitrox Specialty is tricky, as it can be run as a dry course. If you did not take any dives during the Nitrox course then they cannot be counted as an Adventure dive for AOW.
So without knowing this you only have 2 adventure dives possibly 3. You need 5 for AOW, so you can take 2 more but they have to be Deep and Navigation. Now to circumvent the manual requirement you can request to these as seperate Adventure Dives,
don't ever mention the words Advanced Open Water course; as soon as you do they shop is obligated to sell you the Manual.
Still need the text for the adventure dives to be credited towards advance. Need to complete the knowledge reviews for each dive done. Or do it online via PADI eLearning.
My advice. Find two seperate dive centres, do one adventure dive at each. Then after the 2nd, turn around in the shop gobsmacked and say 'hey, what d'ya know, that's 5 adventure dives!' ask them to certify you as AOW.
That can work.Would need to give the shop proof that the dives were done and signed off by a current PADI instructor of course and then pay the certification card fee that can be around $25.
