I split this topic, Crafty, because the original poster was talking about frequency stepping, and you're talking about decibel stepping. If you have a feature idea regarding anything in the future please make a new topic, don't co-opt an existing one.
That said, I'm not sure this is a feature idea or a bug report. I believe I can speak for the developers when I say that 1dB stepping size is a no-go. That's too coarse.
What I suspect you're seeing is (and I don't have a Clip to check on, my Nano is my smallest screen) is that you don't have enough screen real estate to display an indication of the 1/2 decibel stepping in the graphical EQ screen. Perhaps this is a bug, perhaps it is intentional behavior...
