Given the list of options, it's obvious that the values are to be rounded to a full multiple of 25%. So "0%" actually means "less than 12.5%" and "100%" means "more than 87.5%".
If the options were taken at exact value, it's practically guaranteed that none of the options fits. To start with, the 50% option being exactly true requires that the number of posts is even, therefore every second post it is guaranteed not to hold, and the 25% and 75% options can only hold if the number of posts is a multiple of four, that is, only once in four posts it is possible that one of them holds exactly.
