There is some variation in how much you get back. Sometimes you'll sleep well, sometimes you won't. Sometimes it's hot or stormy, sometimes it's not. But you will get more and more stamina from sleeping the higher your base stamina is. If you have the bedroom maxed out plus the healing implant, plus 100 stamina you can go to sleep at like 2 stamina and wake up with 100 or close to it.Thanks for your answer, but all the thinks you mention are well know to me. Bathing, the Spa, the healing when you arrive at home from Caitlin... It´s not my first run.
I´m just asking for the cutting point. The training capability it´s an scarce resource, If you train Stamina you don´t train combat, or science, and you must choose your priorities. If I must invest 35 training sessions (from 41 to 75) before getting any sensible benefit, that´s a lot of investment
In a new game, I train stamina twice a day every day until I get to 80. Then I usually take a break from stamina training to do a few other things like boost my medical skill a little, maybe train up melee a bit, etc. But soon after that it's back to stamina training again until I hit at least 100. You're going to want to train stamina on your slaves anyway.
