The earnings passage under Rooms and Teams states
If you have multiple buildings or organizations in a settlement and they can generate the same kind of capital, you don't have to roll for them separately—you may add all their capital modifiers together and attempt one check for that kind of capital. If you spend a downtime day earning capital on your own, you may add your building and organization bonuses to your roll instead of rolling separately for yourself and each of your businesses or organizations.
Now take the alchemy lab for example, which earns +10 Magic. Let's say I own two of them in separate buildings.
I can do either of the following
- Sum their bonuses, and take 10 for a total of +30, and earn 3 Magic
- Take 10 on their checks separately, yielding +20 and +20, and earn 4 Magic
These two options are clearly not equivalent, yet I can choose between them as I like? What if I own a hundred alchemy labs? They're not expensive at all even for a relatively low level party. It seems like a player (or even an entire party, at GM discretion?) should have to sum all bonuses of like type in a settlement, to avoid getting redundant opportunities to take 10 in the same day.
Is this an oversight or by design?
