The key to the first 10 questions is to do what you should be doing throughout the entire test - namely you need to get the questions right that you can get right.
You see if there are really tough questions in the first 10 and you miss those it is not a big deal. You will have the opportunity to work back up to those 80th or 90th percentile questions. The problem comes in missing lower difficulty questions out of the first 10. It is true that if you miss lower difficulty questions on the first 10 then the computer will not trust you to get those questions right and so will present you with lower level questions until you have gotten enough of these right in order to move up.
Basically you goal on the first 10 is not to miss "easy" questions.
By the way, the chart that is displayed lacks some very important information. What is the difficulty level of the questions missed? It is not a revelation to say that one person can miss 11 questions and another miss 9 questions and the one who missed 11 questions scores much lower. The questions missed could have been less difficult.
I have a problem with these examples where someone only tells you how many questions they missed or which numbers. Let me see the level of the questions and that will tell the tale. For example, you can miss 12 questions on Quant and score a 49/50. You can also miss 12 questions and score more like 43. That is a big difference. The importance is not the number of the question missed but the level of difficulty.
Here is an article on GMAT scoring for you to read - please read it. And remember the first 10 question are not different from any others - you want to get the questions right that you can get right, the rest will take care of itself.
