I can't remember where I read it, but what settled the issue was this
more reasonable sounding advice: it's not good for the battery for it to
sit fully charged for a long time.  It's also not good to drain it every
day.  Therefore keeping it between 30% and 80% should be a good
guideline for regular use.  If you're not going to use it for a few
days, you shouldn't charge it all the way.  If you're going to use it,
having it charged below 30% means you run the risk of draining the
battery while you're on the bus.

I generally charge mine all the way up when it gets below 20% if I'm
near an outlet; I use the laptop almost every day.  About an hour
charges it all the way from 20%-30% to 99% (this is an x100e).

Thanks for doing the research!
