I have a seething hatred for UX that forces every setting to be in nonsensical chunks for no reason. Bad designers somehow think that it's "simpler" but it's just not. It's pushy, annoying and disrespectful to users to presume you know what values they should prefer. A good UX designer can always find a way to let users fine-tune settings to suite their individual differences.
