First know your total (you can change it as you go through figuring out your character but once posted it is final unless you talk to a admin about it) then divide by total levels. here it is so you divide (the number you have chosen for your total) 750(is my example number) by 100 to get how many points average you get per level. then you take the level you are starting at and multiply your result by the starting level. In this case it would be 7.5. When you level you get your average but if it is a decimal number then the left over is carried over into the next level and the next till it makes a whole. example if your stat gain is 6.2 every 5th level you would get an additional stat gain.
