What's been missed here is that driving under 50% is more stressful to the battery than driving between 90% and 50%. (How much more is open to question but then so is the stress difference between charging to 50% or charging to 90%, neither the driving nor the charging will be zero). The first two years I charged to 80% and saw the range go down. The second two I charged to 90% and saw it go back up. I charge to 100% before a trip, but leave shortly after the charging stops (or sometimes before charging stops depending upon how good I've timed it). This also ensures the the balancing circuits activate.
A larger battery will always be stressed less than a smaller battery for any given operation condition.
After over four years and 94K miles, as best I can tell, there is less than 3% difference from new. In other words, it's not really worth stressing over because of Tesla's good battery management system. Just don't leave it sit at very high or very low SOC and plug it in daily and your battery will be fine.

Charge to 100% when you might need it at 100%. Don't when you're sure you won't.
