I'm not sure that I understand your point right now.

With 300-500 cycles at 100% utilization, a 300 mile car would have degraded its battery to 70% after 90,000 - 150,000 miles. With 2,000-2,500 cycles of 25%, the car would have traveled 150,000 to 187,500 cycles.

That seems like a significant improvement to me?

Your point about supercharging is similarly valid, but also a little misleading. The big factor there is temperature and the Tesla packs use active cooling to reduce the hit from more aggressive charging. I'm not sure that anyone has really seen a significant impact from this.

Basically, battery quality and management matter. Tesla does those things pretty well.
