Barry, Thanks for that thorough answer. I really appreciate the effort.

I got the ~300 (which probably should have been 300-500) charges from an online tech channel I used to watch: Leo Laporte's tech.tv. This question frequently came up, and that was his stock answer.

I always wondered how one should count a charge to a battery that was only slightly discharged. I worried that charging a battery that was still 80% charged would count as one full charge against that total number of charges the battery would accept. Your explanation makes good sense and is good news. I now understand that charging a 70% already charged battery counts as only about one third of one of those 300 or 1000 or however many charges that the battery will accept. That piece of information is very valuable to my battery charging concerns. I won't be leaving my devices plugged-in anymore.

Thanks again.
