I think you are totally right there. I pulled 50% out of the air.
Think of it more like, when you hit 50% you start thinking about plugging in, but by the time you actually get around to it, it might be closer to 30%.
As to only using 40% of the battery's charge capacity -- the idea here is not to religiously follow the 30-70% rule so much as do it when it's convenient rather than intentionally draining the battery flat when you could have plugged in easily. And also you have the full capacity when it isn't convenient.
And if you accidentally drain it flat once or twice a year, you've fulfilled the retrain schedule too. But to do it on purpose seems wasteful.
