I'm home all day, most days. Am in Greece.
Currently, Day setting is
and Night setting is:
When I will be unable to check on my game for an extended time during the day, it depends how long that period will be. If 3 hours or so, I tweak Day camp to take 3-3.5 hours by swapping some lowest green for highest blue in my backpack.
If I will be out for 5 or 6 hours, I will tweak Night setting by swapping blue out and green from backpack in.
If you just change to your Night setting (assuming it is set for about 8 hours), you will be disappointed with the amount you get for a 4 hour absence. That is why I tweak the regular settings for the time I estimate I'll be out.
To make swapping easier, I have each row set up in numerical order, all blue on one side, all green on the other. Then I can quickly swap greens worth, say, 200-206 each, and I know I'm not taking out a higher value green than I need to. When I increase the Day camp to run for 3.5 hours, the top row looks like this (most rows change and with every row set up all greens and all blues each in number order, one or two rows might not have anything within the range of values I am changing):
Note: for temporary swap like this, I don't worry about exact order of the swapped-in tiles. The temporary blue tiles will be swapped back for green once I'm back from the outing. It is the regular setting set-up that needs to be in order to guard against putting away a higher-value tile than necessary.
