Equally important is building on a diverse array of different numbers.
Equally important is building on a diverse array of different numbers. If all of your settlements are clumped around a few numbers your ability to gather resources will be very uneven – you might collect a ton of resources when your numbers are rolled, but will go long stretches without collecting anything. By building on a range of different numbers you have much better odds of collecting some resources with each roll. In fact, if you have settlements on a 4, 5, 6, 8, 9, and 10, the dice will land on one of your numbers 2 out of 3 times!
