It feels like the chat feed is a gathering of some hardcore dominants. Dear fans of femdom who understand the mechanics of the game well, your time has come.
Please tell me, who really knows what actions are currently necessary but sufficient for sub Kane to take to end up at levels K1, K2 and K3? And is it even possible? It's just that no matter how I screw up, Olivia appears who pulls me out of any shit by the ears, and "my" is a pretty evil young lady, I must say.
		
		
	 
Good/Evil doesn't matter at all for rankings. 
Kane and Olivia's long-term relationship (
sis_team) actually doesn't really matter all that much for Kane's rank 
yet either, with one exception... This is because so far it only affects the first evaluation (on both sub and dom routes) but has absolutely no bearing one the second evaluation, which is the only important evaluation thus far. (The one exception is if Kane goes from k4->k5 on the first evaluation). The first evaluation is pretty much worthless besides that one exception lol.
There are 2 variables related to both Kane/Olivia's relationship and his rank:
1) 
sis_team, which I mentioned above.. it's a long-term tracker for their bond obviously and affects the first (useless) evaluation, but will almost certainly affect their relationship more importantly down the road on both dom/sub routes.
2) 
sishpts, which so far only matters on the sub route, and is a tracker of both their bond but mostly Kane's performance and affects the second (important) evaluation on the sub route.
You asked about the sub route in particular though, so that's what I put below:
First evaluation:
(Olivia 
likes you if you have at least 2 sis_team points. She doesn't like you if you don't.) 
-> If Olivia likes you, and you've done very well (Delilah recommends k5), then you'll be moved up to k5 (which puts Kane's on an entirely different route).
-> If Olivia likes you, and you haven't done very well, then you'll be k4 no matter what (even if Juliette demoted you to k3).
-> If Olivia doesn't like you, and you've done very well (Delilah recommends k5), then Olivia will refuse to promote you to k5, and you'll be stuck at k4. 
-> If Olivia doesn't like you, she will follow Delilah's recommendation. (Which could be stay at k4, or demote to k3 or demote to k2 if you were already k3)
Second evaluation:
-> Is entirely based on 
sishpts, which are negative points that you can gain both with your behavior around Olivia 
and your performance in your tests after the first evaluation... 
-> If you gain very high sishpts, you will be placed in provisional k1. If high, then k2. If medium, then k3. If low, then k4. (again, your previous rank has no bearing on this, nor does Kane's relationship with Olivia... only 
sishpts... Yes, you can go from k4 to provisional k1 here lol)
So if you want to get on ranks k1(provisional)/k2/k3/k4 on the second evaluation, you'll need to get the appropriate amount of 
sishpts, which you can start collecting immediately after the first evaluation:
-> When you wake up in her house, you can be disobedient to her, which will gain you 
sishpts.
-> Then there are 3 tests... With Olivia/Juliette, with Olivia/Veronica, with Dominique. Doing poorly on these tests will give you 
sishpts.
