GMAT and innate ability

I don't think too many people agree that you can't study your way to a 700.

Maybe it's the politically correct thing to say, I don't know.

I don't think that's right though. I feel that studying and preparing can help you to get used to the types of questions and format of the test. That certainly will correlate to a score boost when compared to no studying/prepping.

That being said, I do believe that people have ceilings. The test does measure ability. That's the point. Grades aren't equal everywhere, so ability has to be measured in a way that's standard.

The returns to studying have to be diminishing. I feel like I got way more from prepping early on them I am now.

I take my test in 10 days and what I am trying to do is narrow my range for variance. I have a good idea of where I think I will score, I just want to reduce variance and narrow in on a score I think I can reach. But, I don't think cramming will help me get 50 more points now.
