hmm, here's another interesting way to calculate grades between styles. Mathematics is not my strong point, but anyway, maybe someone can make a formula?
Let's say regardless of style, the first grade you get (in bujinkan 9 kyu) is equal to 1.0, the highest grade (in bujinkan it is 15 dan) is equal to 100.0. The highest grade in any art is supposed to mean that you are fully learned (to 100%) in that style, right?
So any grade between 9 kyu and 15 dan gets a mathematical number, which corresponds to how many percent you have "mastered the art".
For example 2 Dan in bujinkan is 50% because he/she have gone through 12 grades and have 12 grades left until highest grade. You can do the same math with all grades in all styles and get a more fair way of comparing grades between styles.
You get it?
