The Car, 2017 facelift Model S 75 (unlocked from 60) with 50,000 miles on it. I got it at 35,000 miles

Things I (think I) know

• The Superchargers at rated at 130KW/h or better, they consist of 4 chargers in a stack, on your own you get all of them, when you someone joins you lose a charger, then as you increase your charge and lower the rate you lose others in the stack to the other terminal.
• There are different chargers in the cars depending on their age
• There is different performance of different battery packs
• There is different performance based on number of charges
• There is different performance based on how full the battery is
• There is different performance based on battery temperature
• There is speculation that Tesla lowers the rate on regular SC users

If all that is right, how do I troubleshoot the fact that I've never seen charging faster that my S75, I've watched it from 10% to 100% at the superchargers and the best I've ever got is 78KW/h and thats at about 35% charge?

Do I have a wearing out battery? and old charger? Tesla Throttled? Thoughts

I was hoping for a survey on your fastest charge rates with car and age to work out if I'm just average?
