you can jump your brawn x brawn, so if you have a brawn of 5 (for easier math) you can jump 25 squares on the first page you will move 10 squares in the air, ditto on the second page, on the third page you will move your last five squares and land.
so if my 5 brawn leaping character wants to jump and attack in one panel, the most he is jumping is 10 squares. any more and he is airborne for more than one page.
