You keep your SoC above 60% about 9% of the time.

Above roughly 60% SoC, the cell sits in an elevated calendar-aging zone, so a lower resting SoC is gentler when you park for a while. The whole 60 to 100% range seems to be roughly as bad according to studies.^1,2,3

You spend about 0% of your time above 30 °C.

Heat speeds up calendar aging, but on your nickel-based battery the effect is fairly modest at a normal resting SoC. Aging roughly doubles between 25 °C and 50 °C.¹ The heat from fast charging is not dangerous because it is only brief. Your Tesla warms the pack to over 50 °C to charge faster.
