Default TPS voltage

Wich is the best way to tell how far the TB is really open?
Would it be the TB voltage or Throttle %?
I am thinking that after you reset the throttle %, that even though the TPS % is zero at idel, it would still be open a little (you can tell by the set screw) and the position where zero tps % has just changed.

I am trying to figure out why my idle is hanging a little. I have stit and ltit close to zero, and redone the BRAF. Zeroed the TC and TF, and I still get a hanging idel at 1500 rpms (set at 1050).
If TPS voltage shows how far the TB is open in relation to voltage and not considering where you reset it to, then I would be getting a little airflow at .63v, maybe enough to get the car to have a hanging idle.
