trainboy2019 no worries- thanks for the response! If I can figure out where to find you on discord (what server- I dont see ya on the f95 one) I'll gladly switch to there.
I've taken great strides to plan a route (I'm nerdy like that) including trying to get Lena exp mostly during twilight, since shes the only girl you can get exp for then (heartbreaking when she's asleep!) And working to align each girl's schedule around the days they lvl up.
With skipping a bunch of content I normally like to see (since it doesnt work towards the good ending,) I was able to get the following in 50 days:
* Elaine, Lena, Rika, and Gwen to lvl. 4
* Jace, Kay, Lily and Emma to lvl 3 (but no mind rooms complete.)
* 20 knowledge.
So, not only did I not make it (and see no way of doing so,) I also intended to skip all of the mansion, the beach party, and the 3 inn girls.
It takes about 6 days per girl to get to lvl 4. If a time of day (morning, noon, eve, or night) is a session, it's:
* 4-5 sessions to lvl.1 (depending on if they get exp upon being controlled. Also Elaine can be done in 3 sessions via the bath scene.)
* 6 sessions to lvl 2 (4 bjs and 2 work sessions)
* 5 sessions to lvl. 3 (all sex sessions)
* 4 sessions to mind room 1 (all sex sessions)
* 8 sessions to go from mind room 2 to mind room 5 (50 exp, 2 girls at once: Elaine/Lena, Jace/Kay, Gwen/Rika, Lily/Emma).
That's about 20 sessions per girl to get to mind room 1 (or 5 days).
Mind room 2-5 is 8 more sessions (2 days,) but since you can get 2 girls at once we'll say 1 day per girl.
That all is to say you need at minimum 6 days to get a girl to lvl 4, or 48 DAYS TOTAL to get all 8 girls to lvl. 4.
On top of that, you need 20 sessions for school (5 days total,) and also have to factor in wasted sessions needed to advance a girl (like how lena takes 3 nights of tea drinking, for example.) I could be missing something here, but I think it's Lena, Elaine, and Jace take 9 sessions altogether, but to be safe we'll say 12 sessions (3 days worth of time.)
Add in wanting to do mansion, inn, and Kat activities, and I recommend increasing the time limit to 63 days (9 weeks.)
