... Okay, what you said doesn't even begin to apply to DDR at all. You don't hold a quarter step any longer than an eigth step or a sixteenth step. It's not the same as actually playing an instrument. Just give up, you don't know what you're talking about.
All that I've been trying to say is that DDR has no 1/16 or 1/8 arrows. A 1/8 is half of 1/4, and 1/16 is half of 1/8. With this in mind is there any arrow shorter than the 1/4? NO. So there is no 1/16, or 1/8 arrows. The original post was fixed and now says what I've been trying to say, go and read it.
And look at this picture
