Quickly eyeballed my notes (they're old, with many revisions as I worked but basically):
Ep6 is where K9 is set and you need max Domonique for the K9, otherwise you're K8 or less.
Player can only receive max Jul or max Ver pnts (between the two) and needs max Dom's pnts too.
It takes 8 DomThronePoints to get K9 ("Dom" meaning dominate in this variable).
The only way DomThronePoints are awarded:
DomThronePoints(8) to KLevel. This is the only way to make k9 True:
DomThronePoints are the absolute key here, you must have 8 (or more technically which isn't possible) to get to K9.. it's the only way the variable is ever set to True in the entire VN to date.
Edited for more description and clarity.
