As Tom T said, it is time and cycles that degrade a battery. I would add to that, leaving the battery at a high state of charge isn't the best for the battery as well. So if your not using the car that much just don't top it off when your done.
I find the biggest change I see in capacity or Hx is when I run the battery down pretty low, to LBW or VLBW. But honestly I don't think that "helps" the battery it just gives the car a better picture of the actual battery capacity and adjusts accordingly.
I wouldn't say it's "for no useful reason". By cycling the battery more this past week, my stats have increased 3%. I need as much usable capacity on the weekends as possible and lately I can really tell the difference compared to a few months ago.
I'm not exactly sure how to ask this...
So if I go back to only charging 1-2 times per week and my stats stay at my low (down 10-13%), will my usable capacity stay the same for longer vs. higher usable capacity in the near term and lower in the long term?
Say 1 year from now, if I cycle my battery more (and the stats keep going back up and stay at a reasonable level), will I have more usable capacity than if I don't?
How about 2 years? I can imagine 2-3 years, the car would have less usable capacity from time degradation but maybe not 1 year.
I'm leasing and do not plan to buy the car so I'd rather have more usable capacity in the near term vs. long term.
I usually charge from around 30% and rarely hit LBW or VLBW. I never let the car sit at more than 80-100% for more than 1-3 hours.
