The schools you listed do have average scores in the low 700s - but remember what "average" means. Not everyone who was admitted has scores at or above the average, right? :)
That's not to say that you shouldn't go for a really high score, but be aware that no school requires that. In fact, by definition, many people with scores lower than 720 are getting into these schools, too. If you tell yourself you have to get 750+, you're ratcheting the stress up so high that you might fail just from that! It's a lot better to think "I'm going to go for a 700+, and if I can get to 750, I'll be ecstatic!"
We won't download and open any files for security reasons - but, actually, you shouldn't be sending me all of the data anyway. Once you've done your analysis, synthesize it. Then tell me, for example, "I've got a timing problem, as evidenced by A, B, and C (cite some data points) and I plan to do X, Y, and Z in order to fix it." I'll then tell you whether I agree with your analysis and your plan and also tell you anything else I think you should do. :)
[A private tutor would look through everything for you - so if you do feel you need more support, that's one option. I'll just let you know that I also make my private tutoring students do their own analysis as I do my analysis; then, we get together to discuss what we both found. You learn a lot more when you figure things out for yourself.]
The verbal section is the last section, so think about how you're spending your mental energy on the earlier sections, especially IR and quant. Because you need to have enough mental energy left to last you through verbal, there are times when the best decision is to let an IR or quant question go, with that eventual verbal section in mind.
eg:
I also sometimes see my self getting caught up in details
That might not cause major timing problems, but it is using up your limited mental energy. Really think about the trade-offs as you spend your mental energy - it's a finite resource.
Even if you're going for a 51 on quant, you still won't answer everything correctly. One of my students recently guessed outright on 4 questions and still scored 51 on quant. (And I'm sure she didn't just get lucky on all 4 - plus I'm sure she had other questions wrong as well.)

Then GO for 1 hour, no stopping, no checking email, no getting up for something to eat, etc. Take a 15 minute break, then GO again for 1 hour. Then take a more substantial break.
(Note: I'm specifically NOT recommending that you do what I just described for 3-4 hours. It's actually *more* mentally taxing to study than to take a test, because when you're studying, you're trying to create new memories, not just access old ones.)
