When setting your categories, it’s best to do so using powers of two: 1, 2, 4, 8, 16, and so on.
Yes I agree this will read better. Regardless of which system we use, the mask values ought to be 1, 2, 4, 8, 16 etc… In decimal we will actually use the literals 1, 2, 4, 8, 16.
In binary we will be representing those values using only 0, 1, and the letter b (e.g. 0b100 for 4). It was confusing previously when it said that if you choose to use binary you’ll need to work with 1, 2, 4. You were referring to the mask values, I thought you were referring to the literals. The new text makes it clear you are referring to the category values.
