When you press tab in the gmae and put your cursor on the keystone mastery you can see the bonus physical damage it will deal per level. To test it I just AA a champion at zero and max stacks, substract those two numbers, and calculate the result before resistance. you effectively get 9 bonus physical damage at level 1, 16.3 at level 2 and so on.
