From playing around with it, it seems like what’s happening is this: for each unique percentage that is encountered, Mockaroo generates a true / false value once, based on that percentage. If it encounters the same percentage again, it re-uses the true / false value it generated before.
For example, if Field 1 and Field 5 are both set to be blank 5% of the time, but the other fields are set to be blank 0% of the time, then for a given row:
- If Field 1 is blank, Field 5 will be blank
- If Field 1 is non-blank, Field 5 will be non-blank
- All other fields will be non-blank
