What does the numbers before "Charger disconnected" mean?

Hi,

I'm new to TeslaFi and trying to understand the three numbers below the "Charger Disconnected" sign at the top of the screen:

I assume the first (68%) one is the current SoC.

I assume that the second one (67%) is how much capacity can I use under the current cold weather conditions? I.e. I can only go down to 1% instead of 0%? Is that right?

But what does te /90% mean? :-)) Is that the battery degradation?

Thank you anyone for teaching me these basics. Thanks!
