What you could do is find out what's the 'best' arrangement for each level. So for example if at a certain level you had 20 SPs total split between Boost and SE, graph x against the damage of x Boost and 20-x SE. And just do that 60 times.
There's probably a more efficient way, though.

Make best and worst case scenarios. At best, you have low ATK (say 100) and no secondary stat, and Mastery gets you (1.81/1.54)*1.1 = 1.29x damage. At worst, you have high ATK (say 150) and stats are in a 4:1 ratio, so Mastery gets you (2.06/1.79)*16/15 = 1.23x. Realistically it'll be somewhere in between.
