For now, I'll guess that 80% are below 80% by year 3.
And that is a guess that has no basis in the real world as far as I know. Next month is 2019. That means a fair number of 30 kwh packs will have been on the road for 3 years quite soon. Okay, 80% below 80% by year 3. Let's check back and see how you did with that projection.
My guess has to be amended by the software update which now suggests ~ 24 kWh battery level degradation so 2.5% - 10% a year depending on climate.
