So basically the stat changes occur at midnight (or as soon as a scene ends if you are in the middle of one at midnght.
If the husband has made the wife cum that day, all negative effects that would normally occur either don't occur at all or are very muted. Under normal circumstances, if she has not cum with the husband, it goes down by 1 Satisfaction point per 100 points of Arousal.
If the wife's Arousal is below 100, Satisfaction should go up by 2 points. (I will have to double-check this but I am 90% sure that's right. It's been a while since I coded that particulr function but I believe that is correct.)
Yes it can be tedious and grindy to get it done but it's possible. Not sure whether it's worth the effort to rewrite the code to make it easier to come back from 0. Easiest way is not to let it get that low in the first place, which also takes effort but would be the goal on certain paths (like monogamous). On other paths, it might be more convenient at times to let someone else help her out to make your job easier. Et cetera . . .
For the second point, subsequent orgasms are progressively easier than the first (which you seem to have noticed). I have already added in one cap to keep the actual number of points lower, but I think you are right about adding another cap so that the MC has the opportunity to have sex in one of the (currently) two scenes where she decides to "tip the scales" in her favor.
Oh, I understand your perspective on the "come back from 0". That's not what I was describing on the previous post though. I'm describing a playthrough after two weeks, pleasing her each day (when possible) since day 1, with satisfaction sitting at 61. Then trying to raise that with multiple orgasms in a day.
After reading your reply, I just tried it again from the same save progression, from a friday through the weekend as an example. This is intended as a use-case scenario, employed in software development, to get a gauge on user experience from design.
Friday morning, Aug 25. Satisfaction at 62. Up from 61 after giving 40 orgasms the previous day (10 to get arousal back to 0. 30 after that to push & see how high satisfaction would raise).
From day start: Played through the entire day without spamming/cheating the game (i.e. don't knock on the bathroom door 3+ times at 8 pm. Don't spam the back button. Don't leave the bedroom & return multiple times to attempt to cheat a sex scene).
Fri morning: 7 am. Shower. Watch a video or do coffee. Go to work. Come home. Take her out to dinner. Watch a movie with her. Enter bedroom. Talk to her several times. Try to massage several times. Sleep after midnight when she's gone to bed. (No opportunity for sex).
Sat morning 7 am: Satisfaction still at 62. But arousal has already climbed back up in the 100s. Run through the day again. Trying every opportunity to speak with her. Helping with dinner, cleaning, etc. Knocking on the bathroom door only once each time she's in the bathroom. (Three attempts at different times of day). Finish all "speak with her" options in the living room & watch a movie with her. Initiate sex through "speak" option in bedroom. Massage (I spammed here).
Finally at 12:05 am Sun morning, an interactive sex scene triggered. The first one since Thursday night. By this time, satisfaction level dropped to 61 when the day turned over. Wife's arousal is at 200 by now. Give her 10 orgasms to get arousal from 200 to 0. Then 5 additional orgasms after that. Sleep.
Sunday morning 7 am: As expected, Satisfaction still at 61, since it was so when the day turned over. (I assumed here satisfaction would jump to 63 at the end of Sunday night, or at least 62. Even if no more sex is initiated).
Play through the day again just as Saturday: No interactive sex scene triggers this time. Sleep before midnight when all interaction and massage options are worn out.
Monday morning 7 am: Satisfaction still at 61.
What I'm trying to describe here is that even with extraneous effort that goes slightly beyond a reasonable playthrough, you cannot reasonably raise her satisfaction. At best, you can hover it at just above 60. I'm sure if you spammed the bathroom door 5x times or more daily to trigger sex interaction, pressed the back button multiple times to avoid any arousing "Meanwhile's", avoided selecting "Romance" tv shows to heighten arousal, etc, you can eventually climb her up higher. But it's essentially doing so by cheating the game in a very unnatural playthrough.
Even having to give the wife 8+ orgasms daily (6 just to bring arousal down from the natural progression to below 100, plus two more to attempt raising satisfaction level) is quite excessive for someone not playing obsessively to cheat the system.
I'm saying this not to be difficult, but to draw your attention to it.
