Today I noticed a very small amount of juice on the battery contact. I'm pretty sure it came from the center of the 'center post' and not around it. And that's after I heard some light gurgling during the draw. So the sound and visual are probably connected.
The taste seems a bit improved too. Maybe because I've never run the tank down this far there is more air to bring out the aromas. And just before I reassembled I un-twirled the wicks a bit. But I didn't notice the flavor improvement until I was getting under the halfway point in the tank. Another thing is I now have the mouthpiece positioned strait up. The iClear30 seems to operate a bit better like this.
