A real life example why charging to 100% is bad

Here's a nice article about a Tesla hitting 400K miles:

https://www.teslarati.com/tesloop-tesla-model-s-400k-miles-battery-maintenance-cost/

Here's the relevant part:

"Average battery degradation over the vehicle’s first 194,000 miles was around 6% with multiple Supercharger stops every day. Between 194,000 – 324,000 miles, the HV battery degradation was estimated at around 22%. According to Tesloop, this was likely due to the company’s practice of constantly charging eHawk to 95-100%, instead of Tesla’s recommended 90-95%".

Note that they probably drive the car immediately after charging, so the theory "it is okay if you drive immediately after 100%" seems to be incorrect.

I wish Clarity had the option to stop at 90%.

As you learn your charging times it should be fairly easy to calculate and control your charge level. When using a level w charger to consensus is that it only charges to about 90 percent even though the display shows all the bars. I have also read on this forum that it takes about 2hrs 5 min to charge a depleated battery on a level 2 charger. So you can dial in the your desired charge level by programing your charge times. Seach Youtube videos on how to.
