Thosha i don't real understand what you mean for "seeing as not all requisites for scores are known"
the requisite are clear. there are reward for achieve the best in each section, with only ivala rush award the chest with the second best. that score are the final one, and outside ivala rush i don't see much use for this score. the balance is the final one, perhaps a little can change, but will mostly be addition to add some minor past decision effect. usualy they never change the result or the optimization.
ColinHunt i haven't check thosha guide, if the guide don't achieve all the prerequisite i write, obviously don't fit. you need to increase your orgasmic empire score to 30, i think without any investment your score will be ~ 20 so you need to throw some pron in the OE.
