Wow. This is a really great data-driven approach to studying. Kudos for the methodical approach.

There is something missing from your approach that jumps out. You haven't mentioned using study guides at all for content-specific ideas for improvement. You mention reading the OG for ideas. The OG doesn't offer any tactical advice. You need a methods-based study manual.

It looks as though you are categorizing problems using a proprietary taxonomy. I can't make out where the taxonomy is from other than it's not a ManhattanGMAT taxonomy. I would buy and read the strategy guides from the company with the same brand as the data tool you used to generate your strengths and weaknesses assessment. It's important to stick with the same brand because different categorization methods will not jive well with current question categories.

Also, a red flag went up when you mentioned that you had done ALL the OG problems. My intuition tells me that you are likely "churning" through problems. That is, the ratio of time you spend "reviewing" problems is low in comparison to the time you are spending "doing" problems. The ratio that I suggest is 2-review : 1-do. I.e. if you spend 20 minutes doing problems, spend 40 minutes reviewing those problems. Any less, and you are likely missing opportunities for improvement.

Enjoy,
