Let's say you're looking at a letter that's the lowest dot and you've forgotten what it is, but you remember that d is the 2nd lowest and f is the next in the pattern (the 2 highest). For you to be right, it would have to not occur to the average person that they can use their Sherlock Holmesian skills of deduction to figure out they're looking at an e. Or, of course, they could just go through the pattern in their mind until they get to that letter, then they'd have it.
