You took 5 tests in the past 2 weeks?
Stop!

You do not learn how to get better by taking a bunch of practice tests! This is how you learn to get better at the GMAT:
http://tinyurl.com/2ndlevelofgmatNext, you mentioned that you did do the essay. Does that mean that you did not do IR? Don't skip IR in the future. That section tires you out mentally (in fact, I just finished answering a post from someone who wanted to know what to do because he's too tired out from IR and quant when he gets to verbal). That can bring down your performance on verbal. If you are not practicing with IR, then your verbal scores may be artificially inflated.
Some people score about the same on the real test; some people score higher or lower. There isn't a general trend or skew in one direction. It looks like your scores are moving in the right direction though.
Concentrating on either # correct or difficulty level of the mix of questions is not very helpful. In general, as you saw, most people answer about the same # of questions correctly even at different scoring levels.
Further, your performance is not based on any kind of average across the difficulty levels of the questions that you received. The scoring algorithm really is an algorithm - it's very complex.
In general, you're trying to answer the questions that you can answer in a reasonable amount of time, and you're trying to guess and move on when a question is too hard or will take too long.
The RC pattern you mention is likely a mental fatigue issue - and that will be exacerbated when you add IR into the mix. You are probably also spending too much mental energy on quant, by the way - when you hit something that is too hard, let it go. Save that mental energy for verbal!
I'm going to give you the same analogy that I just gave the other student asking about mental stamina.
You manage a division at your company. You have a quarterly budget. It has to last for the whole quarter, so you may decide not to send Sue to the conference in week 3 because you may have a better place to spend that money in week 8. You don't know for sure yet, but you don't just spend all the money right now.
Start taking this attitude toward the test, NOT the "old school" attitude of "I must get this question right."

Then come back here and tell us; we'll tell you whether we agree and advise you further. (Note: do share an analysis with us, not just the raw data. Part of getting better is developing your ability to analyze your results - figure out what they mean and what you think you should do about them!)
