Hi imskpwr,
Based on these additional CAT scores, it certainly appears that your ability level is in the high 600s/low 700s. As you continue to study, you'll have to make a point to focus on your Verbal performance, so that you can remove the 'instability' that appeared in the second GMATPrep CAT.
Most GMAT Experts will offer their own versions of pacing advice, so you might see some variation in that regard. To that end, there are some things that you can do to improve your Verbal pacing:
1) Note-taking is essential on both RC and CR. Try taking notes AS you're reading. On average, an RC passage should take 4-5 minutes to read and take notes on. This will give you about 1 - 1.5 minutes per RC question. CR questions are considerably "thinner", so it shouldn't take more than a minute (on average) to read and take notes. You'll then need time to answer the question that's asked (predict an answer and evaluate the answer choices) - this will also take about 1 minute.
2) For SCs, you need a combination of grammar knowledge and pattern matching (knowing what the GMAT actually tests and spotting the patterns when they appear). A typical SC should take 1 - 1.5 minutes to answer.
3) While there are a few exceptions to the above rules, they are rare exceptions, so you'll have to become a bit more proactive with your work to improve in this area.
As it stands, you're performing at a high level. Keep up the good work.
GMAT assassins aren't born, they're made,
