Free charging, would you charge to 90% regularly?

I think Elon is sometimes misunderstood or taken out of context.
I think what he said was it is OK to charge to 90% if and when you need to.
That also implies that if you don't need the extra range charge to something less like 80%
Any li-ion battery should not sit at a high state of charge for long periods of time.
If you charge to a high rate like 90% or more drive it soon after charging.
A high rate of charge should only be used on trips and only when necessary.
Like you said. Lower is better. If you can live with 80% charge to 80%.

Yep, I used to do 90% daily at work for free. I only used 20% a day ... I've since changed habits and gone with 70-50 range of usage.
