So, let me get this straight. Going up to eleven cost one point if it from ten while going to twelve cost two points if the attribute is eleven?

Yes. This is to prevent players from starting off too powerful by dumping off parameters they'll never use, aka "min-maxing." Every time you level up, you will be able to increase your parameters, so really creating that big gap of values between what you do and don't need will be more and more prominent as you progress.

Silver Fox this will help you too. This chart shows the [b]total[/b] cost of changing [b]any one[/b] Parameter from 10 to a number on the left side of the chart.
The values on this chart [b]do not[/b] stack vertically in any way.
