So when I read your post, the first and most immediate weakness in your study plan is the lack of timing practice. A select few have a natural ability to internally manage their time and do exceptionally well without significant timing practice; however, for the majority of people out there, we need practice in order to train our internal 2 minutes/question clock.
From an initial examination, it seems like you have put in the necessary amount of hours and worked with the appropriate materials. But I have two areas of concern:
1) What were your hit rates? Were you keeping track of the hit rates for each topic? You mentioned that you didn't "feel" that you had any specific weaknesses, but can you quantify that? I kept track of my cumulative hit rates as I moved through my materials so by the end of the OG11, I was able to clearly show that my hit rates for each topic were in the high 80s except for DS, which dropped to 70%. Thus I knew RC, CR, SC, and PS were all about equal, but my real weakness was hard DS questions.
2) Timing practice. You must practice timing. I personally believe that as soon as you learn the basic strategies and move into OG11, you should immediately start timing all your practice. The untrained internal clock will not cut it (unless you have natural talent). Here's the other point: you said you analyzed and brokedown each question - did you do this after each individual question or after a set of questions? Why do I ask this? Because if you do the former, you are reinforcing one of the biggest time wasters on a CAT - that is overanalyzing and overthinking your answers. If you did this, I strongly suggest stopping this practice and instead working in problem sets that are timed. This more closely mimics real testing conditions and forces you to move onto the next question. After you have finished the practice set, then by all means sit down and analyze all you want - the more the better (honestly)!
You have exhausted some of the best materials available (OG11, OG Q, and Kaplan 800). I suggest buying the other respected materials that are left (OG V and the MGMAT books). You didn't mention which cats you used, but I'm guessing GMATPrep and Kaplan based on your original materials. If this is the case, I suggest using the MGMAT and PR cats.
Please provide more details about your study habits and strategy so we can critique it.
Again, don't trust your internal clock. Doing so is like trusting an internal compass, once you get lost, it's very hard to get reoriented and find your way.
