This is probably a noob question, but what does increasing efficiency and persistence do for you? I would have thought persistence would make the "6" multiplier last more than one day, but it still goes down every day even after upgrading twice. I have no idea what the efficiency upgrade does. I've upgraded it twice as well, but don't see any effect. Thanks in advance.
- Persistence slows down the decay of the "6" multiplier so that it goes down by 0.5 or 0.2 per day instead of 1. The last upgrade (20,000 $) stops decay at all.
- Efficiency increases the effect of the girls' supervised tasks. You probably need only a few upgrades if at all since you want to keep your multipliers near "6" anyway and so the girls will be busy almost every day.
Hints :
- As long as you only have Alice, there is no benefit from investing into other categories than Cleanliness.
- In the early game you have enough time to let Alice clean the hotel every day, so you don't need to uprade Cleanliness Persistence asap.
- Punish Alice with an extra shift is the shortest "cleaning" event. Other rewards or punishments may take a longer time.
(It's ca 4h work + 4h reward/punishment but if she gets an extra shift it is just 4h work.)
Once you have unlocked Alice, Sonya and Yuki, your base income per facility is 6 x 6 x 6 = 216.
Note that 5 x 5 x 5 = 125 is only about 58% of the maximum 216, so even a small decay by 1 in all 3 categories costs you 42% of your income. Therefore you want to keep all the numbers as close as possible to "6".
The number of facilities increases based on story progress.
