So it seems as if Tesla has found through additional research, that 90% may have slightly higher degradation than their desirable goals and change the recommendation. But using 65% of a battery on a daily basis is definitely not the norm. And hopefully you are in a climate zone that doesn't get cold. If you were in an area that gets cold, you may end up using near 100% of your battery.
If there was some option to charge at work, even a 120V 15A socket, that would be advisable. 8 hours
@120v will give you about 40 additional miles. That would put you back in a "sweeter spot"
Increasing the slider above 80% is going to give you the nag message, but just read it and take it as is. It's a recommendation.
