Really interesting stuff, thanks for putting it all together - I'm an engineer with a physics background, so I comprehend the technobabble.
In regard to the "bump charging" part, I thought that there were internal mechanisms (hardware or software) in place in Droids that kept them from attempting to overcharge once 100% capacity was reached. Not knowing the actual system schematics, I could be wrong, but I swear I remember reading something to that effect when I first got my D1.
Either way, I think the chart showing percent discharge and number of cycles will help me refine my charging habits. With an anticipated phone life of 2.5 years, I don't want to start encountering significant low battery life issues before then.
